Arrange the following electromagnetic waves in the increasing order of their energy.
(A) infrared rays
(B) AM radio waves
(C) $γ$-rays
(D) Microwaves
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (B), (D), (A), (C)
Energy of electromagnetic waves $\propto$ frequency $\propto \frac{1}{\lambda}$
Order of frequencies: AM radio waves < Microwaves < Infrared rays < γ-rays
Correct increasing order of energy:
(B) AM radio waves < (D) Microwaves < (A) Infrared rays < (C) γ-rays
