Explain how a non-matter-containing electromagnetic wave may travel over space. An electromagnetic wave is made up of vibrating electric and magnetic fields that constantly stimulate each other without the need of materials.
Similarly, How do electromagnetic waves travel through space?
When an atom reemits the energy of an electromagnetic wave, it travels across a tiny area of space between atoms. The electromagnetic wave is absorbed, changed into electron vibrations, and then reemitted as an electromagnetic wave once it reaches the next atom.
Also, it is asked, When an electromagnetic wave travels in free space it suffers from?
Correct Answer: B Only attenuation can happen to electromagnetic waves when they pass across open space.
Secondly, How do electromagnetic waves travel without medium?
Electromagnetic waves aren’t the same as mechanical waves. There are electric and magnetic vector vibrations in them. These vibrations do not need the presence of particles in the medium to propagate. As a result, electromagnetic waves do not need a medium to propagate.
Also, How do electromagnetic waves transfer energy to matter?
The oscillations of electric and magnetic fields transmit energy in electromagnetic waves. The vibrating of air particles or solid particles that the sound passes through transfers energy in sound waves. Energy is delivered by the vibrating of water particles in water waves.
People also ask, Why can electromagnetic waves travel in vacuum or empty space?
Photons are to blame. Because of wave-particle duality, photons are also electromagnetic waves. Photons propagate without the need of any medium. A mechanical wave is a sound wave.
Related Questions and Answers
What can electromagnetic waves travel through that mechanical waves Cannot travel through?
Mechanical waves cannot move into a vacuum, or empty space, but electromagnetic waves can. They need a mode of transportation, such as water or air.
How can you say that electromagnetic waves should travels in free space with the speed of speed of light?
All electromagnetic waves move at the speed of light, which is 3108 meters per second. Other mechanical waves, such as sound waves, need a material medium to propagate. These waves do not. As a result, all electromagnetic waves in free space move at the speed of light. As a result, the solution is option (b).
Do electromagnetic waves travel with the same speed in all media?
Only in vacuum do all EM waves move at the same speed, c. Their velocity changes with frequency in other mediums. Frequency and wavelength are the two main characteristics of an EM wave.
Is most electromagnetic waves are invisible and undetectable?
The majority of EM waves are undetected. In a vacuum, electromagnetic waves transmit energy. The wavelength, frequency, and energy of the electromagnetic spectrum’s regions vary.
Why electromagnetic waves are not deflected by magnetic field?
Light is an electromagnetic wave because it is made up of oscillating electric and magnetic fields and is electrically neutral, meaning it is not affected by them.
Why electromagnetic waves are not deflected by magnetic fields?
Light is an electromagnetic wave, hence it does not include charged particles. As a result, electric and magnetic fields have no effect on light.
What kind of waves can travel through both matter and empty space?
A wave that can move through both empty space and matter is known as an electromagnetic wave.
Do electromagnetic waves transfer matter?
Electrical and magnetic fields oscillate as a result of electromagnetic waves. It’s vital to understand that although all waves transmit energy, they don’t do so with matter.
What wave can travel in space?
Waves of electricity
Is it possible to have a pure electric waves propagate through empty space?
Because they are all basically light of some type, all electromagnetic waves move at the speed of light. So, no, creating entirely magnetic waves is not conceivable.
How does the electric field and magnetic field travel in a vacuum?
A changing electric field generates a magnetic field, and a changing magnetic field creates an electric field, therefore a sequence of changing electric and magnetic fields is formed around an oscillating electric charge, according to the traditional explanation.
Why can electromagnetic waves travel through a vacuum but sound waves Cannot?
Solution: Sound is created when a body vibrates mechanically. To propagate mechanical vibrations, a material medium with inertia and elasticity is required. As a result, sound waves cannot travel across space. Electromagnetic waves, on the other hand, are created by the oscillation of the electric and magnetic fields.
Which of the following is not an electromagnetic wave?
Ultrasonic is the right answer.
Why transverse waves Cannot travel through liquids and gases?
Transverse waves are those in which the medium displacement is perpendicular to the wave’s propagation direction. Because there is no mechanism to produce motion perpendicular to the propagation of the wave, transverse waves cannot flow in liquid.
What type of electromagnetic wave has the lowest wavelength but has the highest energy?
The greatest energy, shortest wavelengths, and highest frequency are found in gamma rays.
Which of the following forms of electromagnetic waves is used mostly in communication?
Radio waves, also known as radiofrequencies, are the most frequent kind of EMF used to transmit information across long distances.
Which describes how electromagnetic waves travel?
Which statement best characterizes the propagation of electromagnetic waves? They have the ability to go through matter as well as a vacuum.
Do all electromagnetic waves have the same frequency?
Ultraviolet light, X-rays, and gamma rays are electromagnetic waves with shorter wavelengths and higher frequency. Infrared light, microwaves, and radio and television waves are examples of electromagnetic waves with longer wavelengths and lower frequency.
Do electromagnetic waves travel at the speed of light?
Electromagnetic Waves’ Speed Through empty space, all electromagnetic waves move at the same speed. The speed of light is 300 million meters per second (3.0 108 meters per second). Nothing else in the cosmos has ever traveled this quickly.
Can we produce a pure electric or magnetic wave in space why?
No, since an electric field cannot directly create another electric field in vacuum, a “pure” electric field wave or a “pure” magnetic wave cannot occur.
How are electromagnetic waves produced and propagated?
Electromagnetic Waves and Their Generation When an electric charge oscillates, it produces an electromagnetic wave that travels across space (vibrating). Consider a charged particle that oscillates back and forth. The fluctuating amount and direction of the moving charge would result in an electric current.
What waves are invisible and undetectable?
The human eye can only perceive visible light, but light comes in many additional “colors” that are invisible to the naked eye, including radio, infrared, ultraviolet, X-ray, and gamma-ray. Infrared light, which is too red for humans to perceive but is all about us and even produced from our bodies, is on one extreme of the spectrum.
Which of the following electromagnetic waves are visible to the human eye?
the spectrum of visible light
Why electromagnetic waves are not affected with electric field but?
Suitable directed electric fields or magnetic fields may deflect moving charges (charged particles). EM waves, on the other hand, do not carry charge and are hence unaffected by electric or magnetic fields.
Can electromagnetic waves be deflected by an electric field?
A magnetic or electric field cannot deflect an electromagnetic wave. Because they are not made up of charged particles. They spread as electric and magnetic fields that fluctuate in both space and time. Was this response useful?
When light travels through a vacuum, it is called “transparent”. It can travel for miles without the light being absorbed or scattered. This is because there are no molecules in space that can absorb or scatter the light.
