KCET
KCET 2021
Electromagnetic Waves
A
Moving with a constant velocity
36%
B
Moving in a circular orbit
27%
C
At rest
8%
D
Moving parallel to the magnetic field
29%
Solution:
Charges moving in a circular orbit undergo centripetal acceleration hence emit em waves. Or when electron jumps from one higher stationary orbit to another lower stationary orbit emits em radiation.
