Question

if the frequency of sound waves produced from the bell of temple is 400 waves per second then calculate its potential energy​

Answer 1

Answer:

Energy in the sound wave E = 1.65 × 10^(-36)

Explanation:

Frequency  of the sound wave (ν) = 1/400 Hrtz

Plank's constant (h) = 6.63 × 10^(-34) J.s

Therefore energy in a sound wave in terms of its frequency is given by

E = h×ν   J

Substituting the values, we get,

E  = 6.6 × 10^(-34) × (1/400)

∴ E = 1.65 × 10^(-36)  J

Energy in the sound wave E = 1.65 × 10^(-36) J
