Question 5

A radio wave of intensity I0 I_0\,I0​ is reflected off a metal sheet. The amplitude of the reflected wave is 15\displaystyle \frac{1}{5}51​ of the amplitude of the incident wave. What is the intensity of the reflected wave in terms of I0I_0I0​?

A

I025\frac{I_0}{25}25I0​​

B

I010\frac{I_0}{10}10I0​​

C

I05\frac{I_0}{5}5I0​​

D

I05\frac{I_0}{\sqrt{5}}5​I0​​
