The bending of light as it changes speed when entering a different medium is A. B. C. D. reflection refraction critical angle diffraction [Default] [MC Any] [MC All]
As light enters a more optically dense medium, A. B. C. D. it light bends away from the normal line. it bends toward the normal line. it goes straight through (doesn’t bend). all the light is reflected. [Default] [MC Any] [MC All]
As light enters a less optically dense medium, A. it speeds up. B. it slows down. C. it maintains the same speed. [Default] [MC Any] [MC All]
The critical angle is the incident angle when the refracted angle is (choose all that apply!) A. B. C. D. a right angle parallel to the boundary tangent to the boundary 90º [Default] [MC Any] [MC All]
Fiber optics is an example that uses A. B. C. D. refraction diffraction total internal reflection resonance [Default] [MC Any] [MC All]
When the incident angle exceeds the critical angle, A. B. C. D. most of the light is reflected. all of the light is refracted. the refracted angle is 90º all the light is reflected back into the incident medium. [Default] [MC Any] [MC All]
The emission of electrons from a surface when light of certain frequencies shines on the surface is A. B. C. D. refraction total internal reflection the photoelectric effect diffraction [Default] [MC Any] [MC All]
Which of the following is/are true of a convex lens (choose all that apply)? A. B. C. D. A convex lens is a converging lens A convex lens is a diverging lens. A convex lens has a positive focal length. A convex lens has a negative focal length [Default] [MC Any] [MC All]
