# Two Waves of the Same Pitch Have Amplitudes in the Ratio 1 : 3. What Will Be the Ratio of Their : (I) Intensities and (Ii) Frequencies - Physics

Short Note

Two waves of the same pitch have amplitudes in the ratio 1 : 3. What will be the ratio of their :
(i) intensities and
(ii) frequencies

#### Solution

(i) Same pitch

(A_1)/(A_1) = 1 /3

Intensities I ∝ A2
therefore I_1/I_2 = 1/9
(ii) Pitch is same ⇒ frequency is same.
