Q.
Electromagnetic radiation of highest frequency is
Electromagnetic Waves
Solution:
Electromagnetic radiations in the order of increasing frequencies is given by $v_{\text {radio }}< v_{\text {micro }}< v_{\text {infrared }}< v_{\text {visible }}< v _{\text {ultraviolet }}< v_{X \text { -rays }}< v_{\gamma-\text { rays }}$
Therefore, $\gamma$ -rays have the highest frequency.
