Microwaves

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.

Microwave Oven

Microwave oven acts on the principle of :

Microwave Link Or Line Of Sight Propagation

When microwave signals follow the curvature of earth, this is known as:

What are "3" microwave safe containers? Glass,Ceramic and ALL Plastics Glass.Plastic and Metal Glass.Ceramic and Microwave Safe Plastic Ceramic,Glass and Metal

From large distance microwaves fall on a long slit of width 5cm. If the first diffraction minima is obtained at an angle 30^(@) form the direct vision slit line then find the wavelength of the microwaves. [2.5 cm]

An observer is moving with half the speed of light towards a stationary microwave source emitting waves at frequency 10 GhHz. What is the frequency of the microwave measured by the observer? (speed of light= 3xx10^(8)ms )
