Problem 29 Medium Difficulty

The index of refraction for red light in water is 1.331 and that for blue light is 1.340 . If a ray of white light enters the water at an angle of incidence of $83.00^{\circ},$ what are the underwater angles of refraction for the (a) blue and (b) red components of the light?

Answer

$\text { Red }=48.22 \text { deg and Blue }=47.79 \text { deg }$

we can, right angle off, refraction. They be for the blue light. So this is for a blue light blue light from Snell's law refracting. Next be that I'm signed. That B is 1/4. In one sign that I want on B, we have 1.34 signed that would be needed refracted necks. And one is one sign 83 from here are that of you? Get so with this equation is 47.8 degrees. So the for the blue light we have that abuse record 47 point eight. For a red light red light, we can write an outlaw and our sign that our is equal to in one sign they don't want again in one season one and theta one is the same where you usually have this one signed 83 and and our is a 1.3 three, uh, 31 sign they are then fed are read it here is a 48.2 degrees
