The highest frequency produced by a man is 1700 Hz and that of a woman is 2780 Hz . The ratio of wavelengths of sound of man and woman are (speed of sound is ` 340 m s^(-1)` )

Options

A. `1:0.60`
B. `1:0.61`
C. `1:0.62`
D. `1:0.59`

Answer

B

Explanation

Wavelength of mans sound `(v)/(upsilon) = (340"m s"^(-1) )/(1700" Hz") = 0.2" m"`
Wavelength of woman.s sound `(v)/(upsilon) = (340"m s"^(-1) )/(2780" Hz") = 0.122" m"`
`therefore` Wavelength of man.s sound : Wavelength of woman.s sound `=0.2" m": 0.122" m" = 1: 0.61`
