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 rays bend as they pass from one medium to another?
Reflection
Refraction
Diffraction
Dispersion
2. The angle of incidence is equal to the angle of reflection. This statement is known as:
Snell's Law
Huygens' Principle
Law of Reflection
Law of Refraction
3. When light passes through a prism, it separates into its constituent colors due to .
4. The property of light that allows us to see objects is its ability to off surfaces.
5. Explain the difference between specular and diffuse reflection. Provide an example of each.
6. Draw a ray diagram illustrating the path of light as it passes from air into a denser medium (e.g., water) at an angle. Label the incident ray, refracted ray, normal, angle of incidence, and angle of refraction.
7. Light travels faster in water than in air.
True
False
8. The index of refraction is a measure of how much a medium slows down light.
True
False
Match the term on the left with its definition on the right.
9. Critical Angle
a. The spreading of light as it passes through an opening or around an obstacle.
10. Total Internal Reflection
b. The angle of incidence beyond which all light is reflected back into the denser medium.
11. Diffraction
c. The complete reflection of a light ray back into its original medium.
12. Observe the image below showing light passing through a prism. Explain the phenomenon occurring and how it relates to the concept of rays.
