Question on: WAEC Physics - 2001
Surface waves travelling in deep water at 15ms-1 are incident at a shallow water boundary. If the angles of incidence and refraction are 45o and 30o respectively. Calculate the speed of the waves in shallow water
A
8.1ms-1
B
10.0ms-1
C
10.6ms-1
D
22.5ms-1
Ask EduPadi AI for a detailed answer
Correct Option: C
n = (\frac{\sin 45}{\sin 30} = 1.4142)
n = (\frac{15m/s}{x})
x = (\frac{15}{1.4142}) = 10.6m/s
