Microwaves and Radio waves:
Microwaves are produced by high frequency electromagnetic oscillators in electric circuits. Microwaves are electromagnetic waves with wavelengths in the range 10 m m to 10 m.
Radio waves are produced by accelerated electrons in suitable electronic circuits. Radio waves have wavelengths from 1m to 100km.
Angle of Deviation: When a ray of light passes by a prism, It changes it's path inside the prism and forms an angle with the emergent ray. This angle is called as the angle of
