Why does a white shirt appear white to the human eye?
The shirt absorbs all wavelengths of light in the visible portion of the electromagnetic spectrum.
The shirt absorbs light wavelengths at the red and blue ends of the spectrum but reflects colors in the middle of the spectrum.
The shirt reflects all wavelengths of light in the visible portion of the electromagnetic spectrum.

The archer fish is able to see insects above the water's surface. The insect appears to be in a different position than it actually is.
Which property of light is demonstrated?
absorption
reflection
refraction

The electromagnetic radiation from distant stars and galaxies reaches Earth even though particles cannot travel through the vacuum of space. What explains how this occurs?
Electromagnetic waves do not require a medium to travel through space.
Electromagnetic waves move quickly enough to travel through space without a medium.
Electromagnetic waves reflect off of planets’ atmospheres to reach Earth.
Electromagnetic waves vibrate so quickly that they create their own medium through which they travel.

Echoes are a type of sound wave. How are echoes created?
absorption
reflection
refraction

What colors will the objects appear?
Object A will appear red, and object B will appear green.
Object A will appear black, and object B will appear white.
Object A will appear white, and object B will appear black.
Object A will appear green, and object B will appear red.
James ties one end of a rope to a tree and stands at a distance from the tree such that there is slack in the rope. While holding the rope, James moves his arms up and down, creating the formation of a wave as shown. What is the medium that the wave is traveling through?

One at a time, Sam observes different-colored objects using three different-colored filters. His observations are shown in the chart.
What can be inferred from the data?
Color filters absorb all colors that pass through them.
Color filters reflect all colors that pass through them.
The color of an object is the light that is reflected by the object.
The color of an object is the light that is absorbed by the object.
Which factor affects the speed of a wave?
medium the wave travels through
reflection of the wave
transmission of the wave
amplitude of the wave
What happens to light as it passes through a convex lens?
The light is diffused.
The light is reflected.
The light is refracted.

Why does a red apple appear red when placed under a white light?
The apple absorbs red light and reflects all other colors.
The apple reflects red light and absorbs all other colors.
The apple reflects all light.

A speaker produces a sound wave that is directed toward an object. The image shows what happens to the sound wave once it touches the object.
What is true about the sound wave?
The sound wave is reflected by the object, causing an echo.
The sound wave is refracted by the object, changing the wave’s direction.
The sound wave is absorbed by the object, increasing the wave’s volume.
The sound wave is transmitted by the object, reducing the volume of the sound.
Which is not a type of electromagnetic wave?
sound wave
x-ray
microwave
radio wave
