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.

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.
What is the medium for light?
Light, whatever the wavelength, does not need a medium in order to radiate.
Light is not a wave because it does not need a medium?
That statement assumes that every wave needs a medium, which is a false assumption. An electromagnetic wave, such as light, does not need a medium.
Who can we say light does not need to travel in medium?
how can we say light does not need light to travel
What does light not need in order to travel?
It does not need a medium.
What does light need in order to travel?
It does not need a medium.
A Wave that doesn't need a medium?
light; all waves in the EM(electromagnetic) spectrum, including visible light, do not need a medium to travel in
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.
Why don't light waves need a medium?
Light wave flows as a form of radiation. One of the basic characteristics of radiant energy is it don't need a medium. But If it flows through a medium, it won't raise the temperature of medium.
What is the medium for ultraviolet lights?
Light, whatever the wavelength, does not need a medium in order to radiate.
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.
Do light waves need to move through a medium?
No
What types of energy transfer requires a medium?
Its either sound, visible light,xrays.ultraviolet light
