Question

In Figure (a), a beam of light in material 1 is incident on a boundary at an angle ?1 = 38o. Some of the light travels through material 2, and then some of it emerges into material 3. The two boundaries between the three materials are parallel. The final direction of the beam depends, in part, on the index of refraction n3 of the third material. Figure (b) gives the angle of refraction ?3 in that material versus n3 for a range of possible n3 values. The vertical axis scale is set by ?3a = 29o and ?3b = 47o. (a) What is the index of refraction of material 1, or is the index impossible to calculate without more information (enter "0")? (b) What is the index of refraction of material 2, or is the index impossible to calculate without more information (enter "0")? (c) If ?1 is changed to 83o and the index of refraction of material 3 is 2.6, what is ?3?

Explanation / Answer

i have done the same question previously

just change the values
