10Mechanical waves require a material medium for their propagation.
Electromagnetic waves cannot travel through vacuum.
Sound waves propagate due to vibration of molecules.
The medium is the material that vibrates during wave propagation.
Energy of mechanical waves remains constant during propagation.
Speed of mechanical waves is same in all media.
Light from the sun reaches the Earth through vacuum.
Infrared radiation is visible to human eyes.
Radiation transfers energy without any material medium.
Electromagnetic waves can travel long distances without loss of energy.
