Question

b) Two waves A and B are of amplitudes 3 cm and 4 cm respectively. Compare
their loudness. Which sound is louder?​

Answer 1

Answer:

A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. The loudness of a wave depends on its amplitude. The wave having larger amplitude will have higher loudness. So, the wave having amplitude of 6 cm will be louder.
