Radiation doesnt need a medium because it travels through space
A mechanical wave travels through matter.A mechanical wave travels through matter.A mechanical wave travels through matter.A mechanical wave travels through matter.
Light, whatever the wavelength, does not need a medium in order to radiate.
Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.
Light actually travels in waves.This is known to be true because there are only 3 ways that energy can be transferred. As you probably already know, light does not need a medium to travel through because it travels through space. Electromagnetic waves are the only form of energy transfer that do not require a medium to travel through.
Yes, it travels in waves, but it doesn't need a medium.
The material through which a wave travels is called a medium.

Sound and water waves are mechanical and therefore need a medium. Light is an electromagnetic wave which travels as a particle-wave, so it does not need a medium to travel through.
No. Electromagnetic waves travel through vacuum ( ie space where there is nothing)
