Radio waves diffract more easily than visible light waves. Give reason.

A light wave can travel

Lithium is more metallic than beryllium. Give reason.

Radio wave diffract around building although light waves do not. The reason is that radio waves

Consider the following statement A and B and identify the correct answer A) Radio waves diffract around buildings but light waves does not B) To cut down glare of incident light we prefer sun glasses made from polaroids

Solids are not easily compressible. Give reason.

Radio waves and visible light in vacuum have

Assertion : Radio waves are diffracted by buildings Reason : Radio waves are high energy waves.

Give reasons : (a) Diffraction of sound waves is easier to observe than light waves. (ii) We do not observe diffraction from wide slit illuminated with monochromatic light.

The frequency of X -rays, , Gamma rays and visible light wave rays are a, b and c respectively , then

(A) : Transverse waves are not produced in liquids and gases. (R): Light waves are transverse waves.
