Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following best describes the phenomenon when light bounces off a surface?
Refraction
Reflection
Diffraction
Absorption
2. When light passes from a less dense medium to a more dense medium, it bends:
Away from the normal
Towards the normal
Does not bend
Reflects completely
3. The angle of incidence is equal to the angle of in reflection.
4. Snell's Law relates the angles of incidence and refraction to the of the two media.
5. Explain the difference between specular and diffuse reflection.
6. A light ray travels from air into water. Draw a diagram illustrating this phenomenon, labeling the incident ray, refracted ray, normal, angle of incidence, and angle of refraction.
7. The speed of light is the same in all transparent media.
True
False
8. Total internal reflection occurs when light travels from a less dense medium to a more dense medium.
True
False
Match the term with its definition.
9. Critical Angle
a. The bending of light as it passes from one medium to another.
10. Refractive Index
b. The angle of incidence above which total internal reflection occurs.
11. Refraction
c. A measure of how much the speed of light is reduced in a medium.
