Physics Question on Waves

Two waves are represented by the following equation y1−5sin⁡ 2π(10t−0.1x)y_1-5 \sin\,2\pi(10t-0.1x) and v2=10sin⁡ 2π(10t−0.1x).v_2=10 \sin\,2\pi(10t-0.1x). The ratio of intensities I2I1\frac{I_2}{I_1} will be

A

1

B

2

C

4

D

16

Answer

4

Explanation

Solution

I1I2=A12A22\frac{I_1}{I_2} = \frac{A^2_1}{A_2^2}
