Question

Which statement best describes who the period and frequency of electromagnetic was change between gamma rays and microwaves?
a) The period and frequency stay the same.
b) the period increases and the frequency decreases.
c) the period decreases and the frequency increases.
d) the period increases and the frequency increases.

Answer 1

Answer : The period increases and the frequency decreases.

Explanation :    

Gamma rays are the rays having frequency( $\nu$ ) greater than $10^{19}\ Hz$ and frequency of microwave lie between 300 MHz to 300 GHz.

Since, $E=h\nu$

So, as we move from gamma rays to microwaves the energy increases because frequency is increasing.

Also, Time period $T=\dfrac{1}{\nu}$

We can say that as the time period increases, frequency decreases.
