A plane wave generator with a freqenecy of 60.0Hz creates a water wave of wavelength 3.0cm in region A of a ripple tank. The angle between the wave crests and straight boundary between regions A and B is 25.0 degrees in region A and 14.0 degrees in region B. Find the speed of the wave in each region.

f = 60.0Hz

lambda = 0.030 m

thedaA = 25.0 degrees

thedaB = 14.0 degrees

vA = ?

vB = ?

2. Relevant equations

I was thinking to use snell's law, but im not sure how to...

3. The attempt at a solution

General v...

v = f x lamda

v = 60 x 0.030

v = 1.8 m/s

Find vA

vA/1.8 = Sin25/Sin14

vA = 3.14 m/s

Find vB

vB/1.8 = Sin14/Sin25

vB = 1.03 m/s
