Read each question carefully and answer to the best of your ability. Show all your work for calculations and draw clear ray diagrams where requested.
1. Which of the following statements is true regarding the reflection of light?
The angle of incidence is always greater than the angle of reflection.
The incident ray, reflected ray, and normal all lie in different planes.
The angle of incidence is equal to the angle of reflection.
Only diffuse reflection obeys the law of reflection.
2. An object is placed between the focal point and the center of curvature of a concave mirror. The image formed will be:
Real, inverted, and diminished
Real, inverted, and magnified
Virtual, upright, and magnified
Virtual, upright, and diminished
3. The imaginary line passing through the pole and the center of curvature of a spherical mirror is called the .
4. A convex mirror always forms a , , and image, regardless of the object's position.
5. The focal length of a spherical mirror is half of its radius of curvature.
True
False
6. Real images can be projected onto a screen, while virtual images cannot.
True
False
7. Define the terms 'pole', 'principal axis', and 'focal point' in the context of spherical mirrors.
8. Explain the difference between a concave and a convex mirror, and provide one real-world application for each.
9. Draw a ray diagram for an object placed beyond the center of curvature of a concave mirror. Clearly label the object, image, principal axis, focal point (F), and center of curvature (C). Describe the nature, position, and size of the image formed.
Match the mirror type with its primary characteristic:
10. Plane Mirror
a. Diverging mirror
11. Concave Mirror
b. Forms virtual, upright, same-size image
12. Convex Mirror
c. Converging mirror
