Light and Reflection

What is the law 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.

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

Explain the difference between regular and diffuse reflection.

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

• Regular reflection is the result of light interacting with a smooth surface, while diffuse reflection is the result of light interacting with a rough surface.

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

• Regular reflection only occurs with opaque surfaces, while diffuse reflection only occurs with transparent surfaces.

What is the angle of incidence?

• The angle at which a ray of light bends when passing through a medium.

• The angle at which a ray of light splits into different colors.

• The angle at which a ray of light reflects off a surface.

• The angle at which a ray of light strikes a surface.

Describe the process of reflection of light.

• The bending of light as it passes through a medium.

• The emission of light from a source.

• The bouncing back of light rays from a surface.

• The absorption of light by a surface.

What is the angle of reflection?

• Angle between the reflected ray and the incident ray

• Angle between the reflected ray and the surface

• Angle between the reflected ray and the source of light

• Angle between the reflected ray and the normal

How does a mirror produce an image?

• By reflecting light rays

• By bending light rays

• By emitting light rays

• By absorbing light rays

Explain the concept of virtual image in reflection.

• Virtual image is formed when light rays converge in front of the mirror.

• Virtual image is formed when light rays appear to converge from a point behind the mirror.

• Virtual image is formed when light rays appear to diverge from a point in front of the mirror.

• Virtual image is formed when light rays appear to diverge from a point behind the mirror.

What is the relationship between the incident ray, reflected ray, and the normal to the surface?

• The reflected ray is parallel to the incident ray.

• They are related by the law of refraction.

• They are related by the law of reflection.

• They are unrelated to each other.

What are the different types of mirrors used in reflection?

• Plane mirrors, concave mirrors, and convex mirrors

• Flat mirrors, bumpy mirrors, and wavy mirrors

• Red mirrors, blue mirrors, and green mirrors

• Square mirrors, circular mirrors, and triangular mirrors

How does the reflection of light help in forming an image in a plane mirror?

• The reflection of light in a plane mirror forms an image that is upside down

• The reflection of light in a plane mirror forms an image that is in front of the mirror

• The reflection of light follows the law of reflection and forms an image that appears to be behind the mirror.

• The reflection of light in a plane mirror forms an image that is on the surface of the mirror
