In Fig. P.4.30 the wavefronts in the incident medium match the fronts in the transmitting medium every where on the interface€”a concept known as wave front continuity. Write expressions for the number of waves per unit length along the interface in terms of Î¸_iand Î»_iin one case and Î¸_tand Î»_tin the other. Use these to derive Snell€™s Law. Do you think Snell€™s Law applies to sound waves? Explain.
