Question

14. A sound wave has a frequency of 100 Hzand wavelength 340 cm. How long will it
take to move through 1 m?
15. If the velocity of sound in air is 340 m/s,
calculate:
a. The wavelength when the frequency is
256 Hz.b. The frequency when the wavelength is
0.85 m.

​

Answer 1

answer

15 a) wavelength = 1.328m

b) frequency = 400Hz

Answer 2

Answer:

wavelength when frequency is 256 Hz :

Missing: 14. ‎Hzand ‎15.

Given v = 340 m/s ; lambda = ?; f = 256 Hz We know, v = f lambda lambda = vf = 340256 = 1.33 m More
