On what factors does the intensity of a wave depends upon? – InterviewSolution

1.	On what factors does the intensity of a wave depends upon?
Answer» Intensity of a wave I = 2π² n² α² ρ.υ ∴ The intensity of wave depends on : (i) Frequency; I ∝ n² (ii) Amplitude I ∝ α² (iii) Density of a medium 7 ∝ ρ (iv) Velocity of a wave I ∝ υ
