Question

a wave of amplitude 20mm has intensity 1x another wave of same frequency but of amplitude 5mm has intensity 1y ,what is 1x/1y?​

Answer 1

Answer:

(C) 16

Explanation:

Given:

The amplitude of first wave (s₁) = 20 mm

The amplitude of second wave (s₂) = 5 mm

Intensity of first wave = Iₓ

Intensity of second wave =

The intensity associated with a wave depends on the amplitude of the wave.
