I must've flipped them around. The index of refraction for oil is 1.46. But, when I plugged the information into the equation the way you told me,
n1 sin(θ1) = n2 sin(θ2)
1.46 sin(θ1) = 2.18 (sin 25)
θ1= 39, not 35.
Am I using the wrong angle measurement or is it my calculations that...
A costume jewelry pendant made of cubic zirconia is submerged in oil. A light ray enters one face of the zirconia crystal, then travels at an angle of 25 degrees with respect to the normal. What was the ray's angle of incidence on the crystal?
Relevant equations:
n1 sin(θ1) = n2...
