What is the law of reflection?

• The angle of incidence is equal to the angle of reflection.

• The angle of reflection is perpendicular to the angle of incidence.

• The angle of reflection is less than the angle of incidence.

• The angle of incidence is greater than the angle of reflection.

Explain the difference between regular and diffuse reflection.

• Regular reflection occurs when light rays are reflected in a parallel manner, while diffuse reflection occurs when light rays are reflected in many different directions.

• Regular reflection occurs when light rays are reflected in a random manner, while diffuse reflection occurs when light rays are reflected in a parallel manner.

• Regular reflection occurs when light rays are reflected in many different directions, while diffuse reflection occurs when light rays are reflected in a parallel manner.

• Regular reflection occurs when light rays are reflected in a straight line, while diffuse reflection occurs when light rays are reflected in a straight line.

How does a plane mirror form an image?

• By emitting light rays

• By bending light rays

• By absorbing light rays

• By reflecting light rays off its surface

What are the characteristics of the image formed by a plane mirror?

• Virtual, inverted, and upright

• Real, upright, and laterally inverted

• Virtual, upright, and laterally inverted

• Real, inverted, and magnified

Explain the concept of virtual image with respect to a plane mirror.

• The virtual image in a plane mirror appears to be in front of the mirror at the same distance as the object is in front of the mirror.

• The virtual image in a plane mirror appears to be behind the mirror at the same distance as the object is in front of the mirror.

• The virtual image in a plane mirror appears to be at a different angle than the object.

• The virtual image in a plane mirror appears to be smaller than the object.

What is the focal point of a concave mirror?

• The center of curvature

• The vertex

• The focal point

• The outer edge

Describe the difference between a real and virtual image formed by a concave mirror.

• The real image is formed by the actual convergence of light rays, while the virtual image is formed by the apparent convergence of light rays.

• Both real and virtual images are formed by the actual convergence of light rays.

• Real and virtual images are formed in the same way and have no difference.

• The real image is formed by the apparent convergence of light rays, while the virtual image is formed by the actual convergence of light rays.

Explain how a concave mirror can be used as a shaving mirror.

• It forms a real, inverted, and reduced image of the face, making it difficult to see and shave facial hair.

• It forms no image of the face, making it impossible to see and shave facial hair.

• It forms a virtual, inverted, and reduced image of the face, making it easier to see but difficult to shave facial hair.

• It forms a virtual, upright, and magnified image of the face, making it easier to see and shave facial hair.
