Assertion Microwaves are used in microwave oven for cooking purpose. Reason The frequency of microwaves is from 10^(14) to 10^(17) Hz .

Why microwaves are used in radar not radiowaves?

Assertion: Only microwaves are used in radar. Reason: Because microwaves have very small wavelength.

Microwave Oven

Assertion (A): Microwaves are considered suitable for radar system. Reason (R): Microwaves are of shorter wavelength.

Statement 1: Microwaves and not radiowaves are used in satellite communication Statement 2: The wavelength of microwaves is much shorter then that of radiowaves Hence microwaves do not disperse or diffract like radiowaves.

Assertion : Microwaves are heat waves which is used to heat up food in ovens. Reason : In ovens, microwaves heat up the vessel first and food inside gets heated up by the transfer of energy from the vessel.
