Question

Plz solve this appropriately write separate ans for each

Answer 1

i) louder wave is sound wave P because loudness is directly proportional to the amplitude of the wave and here we can clearly see that the sound wave P has larger amplitude.

ii)softer wave is wave P

iii)Higher pitched wave is sound wave Q because it has more frequency and also ,

pitch ∝  frequency

iv)lower pitched is sound wave Q.
