What is order of energy of X-rays (

{E_X}

), radio waves (

{E_R}

) and microwave (

{E_M}

View answer and explanation

Correct option: B

{E_{X\;}} < {E_M} > {E_R}

Option D (

{E_{M\;}} < {E_X} > {E_R}

) is correct because X-rays have the highest energy, followed by microwaves, and then radio waves, based on their frequencies.
