Intensity is proportional to (amplitude)^2 and also intensity α (frequency)^2. Therefore, intensity becomes 2^2/4^2 = 1/4th.

1. 1/4th
2. 1/2th
3. 1/8th
4. 1/16th

Correct answer: 1/4th

Solution

Intensity is proportional to the square of amplitude and frequency. If amplitude is doubled and frequency is quadrupled, the intensity becomes (2^2)/(4^2) = 1/4th.
