Question

This is a timed assignment please answer. Appreciate the work.

The following image shows a wave that moves from one medium to another. In each case, the distance Δχ is the same. medium 2 medium 1 Ax hich statement below is TRUE? Note that the velocity, frequency, and wavelength of e wave in medium 1 are vi, fi, and 2i respectively. The velocity, frequency, and wavelength of the wave in medium 2 are va fa and λ2 respecti vely a. v2 = 4v1 b.fi =46 c. A2 = 2시 d. V1 2V2

Answer 1

medium - 1 lambda_1 = delta x/4 medium - 2 lambda_2 = delta x implies lambda_2 = 4 lambda_1 Since V = lambda/F implies V_2 = 4 V_1 Answer (a)
