JEE PYQ: Electromagnetic Waves Question 2
Question 2 - 2021 (16 Mar 2021 Shift 1)
For an electromagnetic wave travelling in free space, the relation between average energy densities due to electric ($U_e$) and magnetic ($U_m$) fields is:
(1) $U_e = U_m$
(2) $U_e > U_m$
(3) $U_e < U_m$
(4) $U_e \neq U_m$
Show Answer
Answer: (1)
Solution
In EMW, average energy density due to electric ($U_e$) and magnetic ($U_m$) fields is the same.
