Question

A film of oil, with an index of refraction of 1.48 and a thickness of 2.00 cm, floats on a pool of water, as shown in the figure. A beam of light is incident on the oil at an angle, ?i = 54.0

A film of oil, with an index of refraction of 1.48 and a thickness of 2.00 cm, floats on a pool of water, as shown in the figure. A beam of light is incident on the oil at an angle, ?i = 54.0 hat A degree to the vertical. (a) Find the angle ? the light beam makes with the vertical as it travels through the water. hat A degree (b) How does your answer to part (a) depend on the thickness of the oil film?

Explanation / Answer

nair sin theta air = noil sin theta oil = nwater sin theta water

1*sin(54 degrees) = 1.33 sin theta

thet = arcsin(sin(54 degrees)/1.33)= 37.47 degrees

b) doesnt depend on thickness
