Answer:

This is the answer...

Hope it helps ♥️✨

Answer 2

Answer:

It is because of followings:

i) cathode rays have negative charge but e-m waves are charge less.

ii) e-m waves have speed of light but the speed of cathode rays is one tenth of speed of light.

iii) cathode rays are emitted perpendicularly from the cathode surface but e-m waves are emitted in all directions.

iv) cathode rays are stream of negativity charged particle but e-m waves consist of oscillating electric and magnetic field.
