Say True or False:
All electromagnetic waves (X-rays, uv rays. `gamma rays,` cosmic rays etc.) travel with the same velocity.

What are gamma -rays?

Out of X-rays and gamma -rays,which has greatest wavelength?

Which out of the following are electromagnetic waves: X rays, sound waves and radiowaves?

Which of the following belong to the electromagnetic spectrum: alpha -rays, beta -rays, gamma -rays ,cathode rays,X-ray,ultraviolet rays,microwaves,ultrasonic waves,radiowaves,imfra-red rays?Arrange them in order of increasing frequency.

What is the main differnce between X-rays and gamma-rays ?

Electromagnetic spectrum Electromagnetic waves are coupled time varying electric and magnetic fields, propagating in space, with the speed very close to that of light (3xx10^8 ms^-1) . An the orderly distribution and classification of electromagnetic waves according to their frequency or wavelength is called electromagnetic spectrum. electromagnetic waves inclued visible light, ultraviolet waves, infra red waves, X-rays, gamma-rays, microwaves and radiowaves.
