The speed of sound in air is 330`m//s` and that in glass is 4500`m//s`. What is the ratio of the wavelength of sound of given frequency in the two mediums?

Text Solution

Verified by Experts

`V_("air")= n lamda_("air")`
` V_("glass") = n lamda _("glass")`
` therefore (lamda_("air"))/(lamda_("glass")) = (V_("air"))/( V_("glass")) = ( 330)/(4500 ) = 7.33 xx 10^(-2)`
`= 0.0733 ~~ 7.33 xx 10^(-2)`
