In predicting the motion of tsunamis generated in the sea, and interacting with shoreline objects. A ripple tank
is used to generate straight waves in region. A that travel towards region B, which is separated from region A by a straight boundary. The frequency of the generator is 2.5 Hz, and the waves travel in region A with a speed of 15m/s. If the wave fronts in region A strike the boundary at 20°, and the wave fronts in region B leave the boundary at 50°.
a) Use Snell's Law, to find the relative index of refraction between the regions.
b) Find the wavelength in each region.
