While swimming underwater, Jonathan heard the voices of his friends outside the pool, but he could not understand the words they were speaking. Which of the following explains this?

Sound waves change speed when moving from air to water.

Sound waves increase in frequency when they strike water.

Sound waves are absorbed by water molecules.

Sound waves cannot pass through water and are reflected.

The human eye could not see the green color of a leaf without

green light being reflected by the leaf's surface.

red light being reflected from the leaf's surface.

red light being absorbed by the leaf's surface.

green light being refracted by the leaf's surface.

A red apple appears red because it

absorbs all colors of light except red.

reflects all colors of light except red.

refracts all colors of light except red.

is transparent to all colors of light except red.

What property of electromagnetic waves makes it possible to use these waves to transmit information between a space shuttle and NASA mission control centers on the ground?

Electromagnetic waves can travel through a vacuum.

Electromagnetic waves have very low velocity.

Electromagnetic waves are transverse waves.

Electromagnetic waves are all visible to human eyes.

What happens to the path of a light ray as it passes from air into water at an angle?

Its path continues in a straight line.

A person will see a flash of lightning before they hear the thunder that goes with it because

light travels faster through the atmosphere than sound.

the eye is quicker than the ear.

the thunder occurs much later than the lightning.

sound travels faster through the atmosphere than light.

Why are light- colored clothes cooler to wear in the summer than dark-colored clothes?

Light-colored clothes reflect more light than dark-colored clothes.

Light-colored clothes are not as heavy as dark-colored clothes.

In old movies, people sometimes put their ear on a railroad track to see if a train is coming. This works because the iron rail

is connected directly to the train.

Sound A has a shorter wavelength than Sound B. This means that Sound A will

have a higher pitch than Sound B.

have a lower pitch than Sound B.

Imagine a ringing bell set inside a sealed glass jar. Once all the air is removed and a vacuum is created, the ringing sound is no longer heard. Explain why this happens.

Without the air, the sound waves cannot travel to the ear.

The glass prevents any sound from escaping.

The lack of air in the jar causes the ringing to stop.

The pressure of the outside air causes the sound to remain within the jar.

Why does the human eye observe the different colors of a rainbow?

The eye sees different wavelengths of light as different colors.

White light is broken down in the eye into its separate colors.

Different colors of light travel at different speeds to the eye.

The eye sees different colors of light in different locations of the eye.

In order for a fish to see a bug just above the surface of the water, light travels from the insect through the air and crosses into the water until it reaches the fishes' eye. Which statement is true regarding the light as it travels?

It will bend as it hits the water because it slows down.

It will bend as it hits the water because the water particles move slower than air.

It will travel straight from the bug to the fishes' eye because that is the most direct path.

It will travel straight from the bug to the fishes' eye because it will continue to travel at the speed of light.
