The equation of a stationary wave is y ...

The equation of a stationary wave is ` y = 0.04 sin 200 pi t cos (pi x)/(0.3)` with all quantities in SI units. What is the speed of the waves superposed ?

Text Solution

Verified by Experts

Comparing the given equation with ` y = 2 A cos (2pi x)/lamda sin 2 pi nt `
n = 1000 Hz and ` lamda` = 0.6 m
The speed of the waves superposed , ` u = n lamda = (100) (0.6) = 60` m/s
