in general the wavelength of microwaves is more than that of infrared waves

A. Wavelength of microwaves is greater than that of ultraviolet rays. B. The wavelength of infrared rays is lesser than that of ultraviolet rays. C. The wavelength of microwaves is lesser than that of infrared rays D. Gamma ray has shortest wavelength in the electomagnetic specturum Choose the correct option.

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.

The energy of infrared waves is greater than that of

The wavelength of infrared rays is of the order of:

Assertion : Microwaves are better carrier of signals than optical waves Reason : Microwaves move faster than optical waves.

Plane microwaves are incident on a long slit having a width of 5.0 cm. Calculate the wavelength of the microwaves if the first diffraction minimum is formed at theta=30^@ .

Arrange the following electromagnetic waves in the descending order of their wavelengths: (i) Microwaves (ii) Infrared rays (iii) Ultraviolet radiation (iv) Gamma rays Write one use each of any two of them.
