Kepler's 1st law is the law of ellipses
If the amplitude of the wave increases by 4 times, the intensity will increase by 16 times. Option B is correct.
<h3 /><h3>What is the relation between the
intensity and the
Amplitude?</h3>
The intensity is directly proportional to the square of the amplitude of the wave.
Where,
- Intensity
- Amplitude
- constant
Thus, if the amplitude of the wave increased by 4 times,
Therefore, if the amplitude of the wave increases by 4 times, the intensity will increase by 16 times.
