Question

Consider a light ray which enters from air to a liquid, where the index of refraction of the liquid is given by n = . Consider the following three ratios, where each is defined by the specified quantity in the liquid, Lambda ', f', and v' to that in the air, Lambda da, f, and c. What is the ratio of their wavelengths, Lambda '/Lambda da? Lambda '/Lambda da=1 Lambda '/Lambda da=1/2 Lambda '/Lambda da=1/ Lambda '/Lambda da=2 Lambda '/Lambda da= What is the ratio of their frequencies of oscillations, f'/f=? f'/f= f'/f=1/2 f'/f=1/ f'/f=2 f'/f=1 What is the ratio of the traveling speeds, v'/c? v'/c=1/ v'/c= v'/c=1/2 v'/c=1 v'/c=2

Explanation / Answer

   velocity inmedium   v   =   wavelengthin medium * frequency    refractiveindex   n   =   velocityin air / velcoity in medium    frequency does not change in moving from onemedium to another.    a.      (3)   '/   =   1/2
