Physics Chapter Light Quiz

What is the law of reflection?

• The angle of reflection is perpendicular to 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

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

Explain the difference between regular and diffuse reflection.

• Regular reflection is the reflection of light from a rough surface, while diffuse reflection is the reflection of light from a smooth surface.

• Regular reflection results in a scattered pattern of light, while diffuse reflection results in a focused pattern of light.

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

How does the angle of incidence compare to the angle of reflection?

• Opposite

• Smaller

• Equal

• Greater

What is the difference between refraction and reflection?

• Refraction and reflection are the same thing.

• Refraction is the absorption of light by a surface, while reflection is the bending of light as it passes from one medium to another.

• Refraction is the bending of light as it passes from one medium to another, while reflection is the bouncing back of light when it hits a surface.

• Refraction is the bouncing back of light when it hits a surface, while reflection is the bending of light as it passes from one medium to another.

Explain how light bends when it passes from air to water.

• It bends away from the normal

• It bends in a zigzag pattern

• It bends towards the normal

• It does not bend at all

What is the role of a concave mirror in forming an image?

• It can only form virtual images

• It has no role in forming images

• It can form both real and virtual images.

• It can only form real images

How does a convex lens differ from a concave lens?

• Convex lens is thinner at the center and thicker at the edges

• Convex lens is thicker at the center and thinner at the edges, while a concave lens is thinner at the center and thicker at the edges.

• Convex lens has a concave shape

• Concave lens is thicker at the center and thinner at the edges

Explain how the human eye focuses on objects at different distances.

• Diffraction

• Elasticity

• Accommodation

• Refraction

What is the function of the cornea in the human eye?

• To control the movement of the eye muscles.

• To focus light into the eye.

• To regulate blood flow in the eye.

• To produce tears for lubrication.

What is the difference between myopia and hyperopia?

• Myopia is farsightedness and hyperopia is nearsightedness

• Myopia is the inability to see color and hyperopia is the inability to see in low light

• Myopia is nearsightedness and hyperopia is farsightedness.

• Myopia and hyperopia are the same thing
