electromagnetic- light travels in the form of waves
( visible spectrum- 380-760 nanometres)
it is a electromagnetic wave because it does not need matter through
it is right because i am looking at my sci. book and that is what it says
Light is not a mechanical wave it is an electromagnetic wave. Mechanical wave is the one which needs very badly a material medium. But light even through free space can travel.
Electromagnetic!!
The light wave is electromagnetic yes.
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
electromagnetic waves are wave that do not require a material medium for their propagation while mechanical wave requires a material medium for example light wave is an electromagnetic wave it does not require any material medium(depends on air or water)for their propagation i.e even in the absence of air light will still travel... sound wave is a mechanical wave because sound do not travel in a vacuum....
Radio waves are electromagnetic. That's how they can get down here from satellites.
An electromagnetic wave is a wave with electric component and magnetic component. In free space (vacuum), an electromagnetic wave travels with the speed of light, that is 3x10^8 m/s. In fact, light is also an electromagnetic wave.
No. A light wave is a transverse electromagnetic wave.
Non mechanical waves are Eletro magnetic waves. We can devide 2 waves. 1 is mechanical waves & 2 is electromagnetic waves. For example Sound is a mechanical wave & Light is an electromagnetic wave.
An electromagnetic wave is not a mechanical wave.
mechanical
True, because mechanical waves require a medium for propagation.
Sound is a mechanical wave.Light is an electromagnetic wave.
No.
No, a gamma wave is not a mechanical wave. The gamma ray is considered an electromagnetic wave.
A mechanical wave.
Mechanical.
Wave is nothing but a transferring of disturbance. So it needs a medium. But if medium is to be material then the wave is named as mechanical wave. If medium is not to be a material and if free space is enough then the wave is found to be electromagnetic. Sound is a mechanical wave and light is an electromagnetic wave
No. Sound is a longitudinal wave consisting of mechanical vibrations travelling through matter (solid , liquid, gas, etc). An electromagnetic wave (light) is, classically, a transversely oscillating electric and magnetic field and requires no medium in order to travel.
