Arthur keeps a flower vase on the table. He views it through a glass window, and the vase appears the same. When Arthur views the vase through baking parchment paper, he can observe the general shape of the vase, but it appears blurred. What can best explain the blurring of the vase?

light is scattered by the translucent parchment paper

light is absorbed by the opaque parchment paper

light is reflected by the opaque parchment paper

light is refracted by the transparent parchment paper

The image shows the behavior of three light rays (1, 2, and 3) as they encounter a surface.Which option correctly identifies the behaviors of the light rays?

Light ray 1 is absorbed, light ray 2 is refracted, and light ray 3 is reflected.

Light ray 1 is reflected, light ray 2 is absorbed, and light ray 3 is refracted.

Light ray 1 is absorbed, light ray 2 is reflected, and light ray 3 is refracted.

Light ray 1 is refracted, light ray 2 is reflected, and light ray 3 is absorbed.

What occurs when light rays are reflected?

Light passes through an object.

Light is separated into different colors.

Examine the diagram showing an incoming ray of light labeled X traveling through air, making contact with a sheet of glass and the two resulting rays of light labeled Y and Z.Which statement correctly describes the behaviors of the rays of light?

Ray Z was refracted by the glass and transmitted through the glass.

Ray Y was reflected by the glass and absorbed by the air.

Ray Y was refracted by the glass and transmitted through the air.

Ray Z was reflected by the glass and absorbed by the glass

A window manufacturer markets this particular type of door as an opaque glass door.Is opaque the proper term for this type of glass?

No. Since diffuse light comes in, allowing a shadowy image to be seen, the proper term for the glass is translucent.

No. If any image can be seen at all through the glass (clear or shadowy), then the proper term is transparent.

Yes. Opaque glass blocks out effectively all light from passing through it, so no image can be seen.

Yes. Opaque glass transmits some light, but causes it to be scattered, so no clear image is seen.

Examine the behavior of light rays hitting a solid surface.What is happening to most of the light rays?

They are absorbed by the opaque surface.

They are reflected by the mirrored surface.

They are transmitted through the transparent surface.

They are refracted by the translucent surface.

What property of light allows prisms and diffraction gratings to separate white light into its component colors?

The colors have the same speed but different frequencies..

The colors have the same frequency but different wavelengths.

The colors have the same frequency but different speeds.

The colors have the same wavelength but different frequencies.

The diagram shows the transmission of a sound wave through a solid. What happened to this sound wave?

The wave's energy was absorbed.

The wave's energy was amplified.

The wave's energy was reflected.

The wave's energy was refracted.

A beam of light is directed toward two different materials, A and B. The image shows how the beam’s light waves interact with the materials.What can be concluded about materials A and B?

Material A is transparent, and material B is opaque.

Materials A and B are transparent.

Materials A and B are translucent.

Material A is translucent, and material B is transparent.

When is it appropriate for a student to use a convex lens?

when the student wishes to make an object appear larger

when the student wishes to filter out certain colors given off by an object

when the student wishes to make an object appear smaller

when the student wishes to reflect light emitted by an object

Comparing two sets of waves can allow a person to make judgments about the nature of the sounds that produced the waves.Assume that both sets of sound waves are travelling at the same speed. What is the best description of these two sets of waves?

Sound waves from source X are louder than sound waves from source Y, but both have the same frequency.

Sound waves from source X have a greater amplitude than sound waves from source Y, but both have the same energy.

Sound waves from source X have a greater wavelength than sound waves from source Y, but both are equally loud.

Sound waves from source X have a higher frequency than sound waves from source Y, but both have the same wavelength.
