BASIC WAVES

IIT JEE 2015 Forum › General Physics questions › BASIC WAVES

Calculate the coefficient of refraction of a sound wave on the boundary between air and glass. Youngâ€™s modulus for a glass is 6.9 * 10¹⁰ Nm^-2 , density of glass is 2.6gcm^-3 and air temperature is 20Â°C . velocity of sound in air at 0Â°C is 331m/s

find v glass by v=\sqrt{\frac{Y}{d}}

then v_{t}=v_{0}\left[1+\frac{t}{546} \right]

by this u find v₀ of glass. then \mu =\frac{v_{0}}{331}
