Which of the following statement is not correct? (1) All electromagnetic radiations travel with the same velocity (2) Matter waves generally have velocity less than electromagnetic waves (3) Matter waves are emitted by material particles (4) Electromagnetic waves are associated with electric and magnetic fields but matter waves are not.

The electromagnetic waves travel in free space with the velocity of

Speed of electromagnetic waves is the same

Assertion : All electromagnetic waves travel with same speed in vacuum . Reason : speed of electromagnetic wave in a medium is given by speed of light in vacuum divided by refractive index of the material .
