Vedclass · Answer

(A) The electromagnetic spectrum in increasing order of frequency is: Radio waves Given frequencies are:$p$ (frequency of $X-$rays)$q$ (frequency of $\gamma-$rays)$r$ (frequency of ultraviolet rays)Comparing their positions in the spectrum:$1$. $\gamma-$rays have the highest frequency,so $q > p$.$2$. $X-$rays have a higher frequency than ultraviolet rays,so $p > r$.Combining these,we get $q > p > r$.Looking at the options provided,we evaluate the relations:For $p  r$,this is consistent with $q > p$ and $q > r$.Thus,the correct relation is $p  r$.

List-$I$	List-$II$
$(a)$ Ultraviolet rays	$(i)$ Study crystal structure
$(b)$ Microwaves	$(ii)$ Greenhouse effect
$(c)$ Infrared waves	$(iii)$ Sterilizing surgical instruments
$(d)$ $X$-rays	$(iv)$ Radar system

The frequencies of $X-$rays,$\gamma-$rays and ultraviolet rays are respectively $p, q$ and $r$. Then which of the following is correct?
