Question : 10

Total: 40

A source of sound produces waves in air of wavelength 1.65m. If the speed of sound in air is 330ms

^{-1}

, the period of vibration in air is?

200
0.005
0.5
0.02

Solution:

V = $rac{\lambda}{T}$

: v = 330ms $^{-1}$

\lambda

= 1.65m

T = ?

330 = 1.65

T = $rac{1.65}{330}$ = 0.005s
