Question

2. Two tuning forks A and B of frequencies 256 Hz and 192 Hz respectively are vibrated in air
,
If the wavelength of A is 1.25 m, calculate the wavelength produced by B.
[1.67 m)​

Answer 1

Answer :

frequency of tuning forks A = Fᴀ = 256 Hz.

frequency of tuning forks B = Fʙ = 192 Hz.

Wavelength produced in A = ⋋ᴀ = 1.25

Wavelength produced in B = ⋋ʙ = ???

Case 1

V = ⋋ᴀFᴀ

V = 1.25 * 256

V = 320 ms^-1

Case 2

V = ⋋ʙFʙ

⋋ʙ = V / Fʙ

⋋ʙ = 320 / 192

= 1.67 m
