Question

establish the relation between the speed,the wave length and its frequency . if the velocity of the sound is 340 m/s, calculate (1) wave length when freaquency is 256 kg (2) frequency when wave length is 0.85m​

Answer 1

Answer:

v= f ./\ , /\ =1.32,. f = 400

Explanation:

velocity= frequency . wavelength

340 = 256. × /\

/\ = 1.32

f = v/ /\

f = 340/ 0.85

f = 400
