Visible light is a small part of the frequency spectrum of electromagnetic radiation. It behaves both as a wave and a particle (photon), and travels by virtue of the energy expenditure required to "create" it (I use quotes because light, like all energy, cannot truly be created, only changed in form. The light we're most familiar with, sunlight, is released through the fusion of hydrogen atoms into helium, a process that transforms a tiny portion of the atoms' mass into energy).
Unlike sound, which as a mechanical waveform requires a medium such as air or water to propagate, light can instead find its progress impeded or blocked by various media.
What else can I help you with?
A substance that a wave travels through is called a?
The material through which a wave travels is called a medium.
Do radio waves need medium to travel?
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
What types of waves require a medium?
Mechanical waves.For example, sound waves, ocean waves, etc.Many waves need a medium to travel: sound waves, water waves, and seismic waves.Electromagnetic waves do not need a medium.
What is the medium of light?
No medium is required by electromagnetic waves to traverse.
What happens when a light wave does not bounce off of an object?
Three situations may arise when a light wave travelling from an optical medium to another optical medium strikes the second medium. They are as follows: 1. The light ray may bounce off of the medium to which it was travelling with a change in angle.This phenomenon is also known as reflection of light. 2. The light ray may pass through the second medium with a deviation in its angle of incidence. This is also known as refraction of light. 3. The ray may be absorbed by the second medium. If a light wave does not bounce off of an object then either 1. or 2. may happen. That light ray enter the second medium, or it may be absorbed by that medium.
Who can we say light does not need to travel in medium?
Light can travel in a vacuum without the need for a medium. This is because light is composed of photons which do not require a medium, unlike other types of waves such as sound waves that do need a medium to propagate.
What is the medium for light?
Light, whatever the wavelength, does not need a medium in order to radiate.
What does light need in order to travel?
It does not need a medium.
What does light not need in order to travel?
It does not need a medium.
Is medium required to transmit light waves?
No, a medium is not required for light waves to be transmitted. Light waves can travel through a vacuum, such as outer space, without the need for a medium.
Does an elecromagnetic wave need a medium?
No. Light is in the EM spectrum, and we can see light from the sun as space is a vacuum it can be concluded that EM waves do not need a medium.
All waves need a medium in order to travel?
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
Does light travels in waves and is required in a medium?
Yes, it travels in waves, but it doesn't need a medium.
Why is the speed of sound slower then the speed of light?
The sound needs a medium to be transported. Without that medium (vacuum) there is no sound. The sound is blocked by air mulecules. The light does not need a medium.
Do light waves required a medium?
They dont need it, but they can use it
Does light need a medium through which to travel?
Light can travel through a vacuum, which means it does not require a medium to propagate. This is explained by the wave-particle duality of light. While light behaves as a wave and doesn't need a medium, it can also be understood as a stream of particles called photons.
Can light be transmitted with or without a medium?
Light can be transmitted through a vacuum without the need for a medium, such as in outer space. However, in material mediums like air, water, or glass, light can also be transmitted through a process of absorption and re-emission of photons by the atoms in the medium.
