Which letter represents the angle of refraction for the light ray?
Added by Susan A.
Step 1
Step 1: Recall definitions — the angle of incidence is between the incident ray and the normal; the angle of refraction is between the refracted ray and the normal. Show more…

Now label the angles of incidence and refraction: If θ1 is the angle of incidence and θ2 the angle of refraction, which of the following ray diagrams has the correct notation?
Khoobchandra A.
A ray of light travels from air into another medium, making an angle of $45^{\circ}$ with the normal as in Figure P22.7. Find the angle of refraction $\theta_{2}$ if the second medium is (a) quartz, (b) carbon disulfide, and (c) water.
A light ray travels from glass (n = 1.50) to air. If the angle of incidence is 32.5°, what is the angle of refraction? 21.0° 39.5° 41.8° 53.7° The question is misleading because the light ray will be totally reflected.
