Question

A sound wave of wavelength 13m has a frequency of 996 Hz. Keeping the medium same, if the frequency changes to 1328 Hz, calculate the: (i) velocity of sound and (ii) new wavelength.

Answer 1

Answer:the answer is 9.75m,12948m/s

Explanation:

Since the wave is in same medium therefor the velocity will remain constant

i.e,

b)

frequency*wavelength=constant

therefore,

13*996=w2*1328

w2=9.75

b)velocity=frequency*wavelength

=13*996=12948m/s
