In general the wavelength of microwaves is

Plane microwaves are incident on a long slit of width 6 cm. if the first diffraction minimum is formed at 30^(@) then the wavelength of microwaves is

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.

Microwaves are reflected from a distant airplane approaching a stationary observer. It is found that when the reflected waves beat against the waves radiating from the source, the beat frequency is 900 Hz. Calculate the approach speed of the airplane if the wavelength of the microwave is 0.1 H. Velocity of microwave is 3 xx 10^(8)" m/s".
