Multiple Choice

What is the difference between specular and diffuse reflection?

• Specular reflection occurs only on rough surfaces; diffuse reflection occurs on smooth surfaces.
• Specular reflection is always soft; diffuse reflection is sharp and clear.
• Specular reflection is on smooth surfaces; diffuse reflection is on rough surfaces.

• Specular reflection is a type of diffuse reflection; they are essentially the same.

Multiple Choice

What is the difference between concave and convex mirrors?

• Concave mirrors diverge light and provide a wider field of view.
• Convex mirrors focus light and magnify images.
• Concave mirrors provide a wider field of view and diverge light.
• Concave mirrors focus magnify images; convex mirrors diverge light and provide a smaller image.

Multiple Choice

What is the difference between the angle of reflection and the law of reflection?

• The angle of reflection is a specific angle, while the law of reflection is a principle stating that the angle of incidence equals the angle of reflection.
• The angle of reflection is defined as the angle between the incident ray and the surface.
• The law of reflection only applies to curved surfaces.
• The angle of reflection is always greater than the angle of incidence.

Multiple Choice

What is the difference between focal length and focal point?

• Focal length is the point where light diverges; the focal point is a distance.
• Focal length refers to the angle of light; the focal point is the distance from the lens.
• Focal length is a measurement of brightness; the focal point is where light is emitted.
• Focal length is a distance; the focal point is a location where light converges.

A ____ is a transparent object with at least one ______ side that causes light to ______ direction.

Multiple Choice

What does the direction of refraction depends on in a lens?

• The thickness of the lens

• The color of the lens

• The shape of the lens

• The distance from the lens to the object

Multiple Choice

Which describes a convex lens?

• triangular in shape
• more transparent in the middle
• thicker on the edges than in the middle
• thicker in the middle than on the edges

Multiple Choice

If a mirror is curved inwards, what type of mirror is it?

• Concave Mirror

• Convex Mirror

Multiple Choice

How is a convex lens able to project an image onto a screen?

• The lens bends light outward and creates a real image.

• The lens bends light outward and creates a virtual image.

• The lens bends light inward and creates a real image.

• The lens bends light inward and creates a virtual image.

Multiple Choice

Which model shows what happens when light passes through a convex lens?

Multiple Choice

The point at which light rays converge after passing through a convex lens is called what.

• The Horizon Point

• The Point Break

• The Focal Point

• The Perspective

Multiple Choice

When looking through a _____lens, the image appears upside down and larger.

• Absorption

• Concave

• Diffraction

• Convex

Multiple Choice

Which of these describes a concave lens?

• focuses light

• breaks light down into bands of color

• spreads light out

Multiple Choice

How does a concave lens differ from a convex lens?

• A convex lens is another way to describe a plane mirror; a concave lens is curved

• A concave lens is curved inward on both sides; a convex lens is on only one side

• A convex lens has a thick center and thin edges, a concave lens has a thin center and thicker edges

• A convex lens has a thin center and thick edges. a concave lens has a thick center and thinner edges
