According to Willebord Snell, light passing from air to glass will cause the light to

accelerate while it is in glass

How does light behave as it enters these mediums?

continue its path as straight line.

When a red light ray travels from air into a glass block, its

velocity decreases and its frequency stays the same

velocity increases and its wavelength decreases

velocity decreases and its frequency increases

velocity remains the same and its wavelength decreases

When light passes at an angle to the normal from one material into another material in which its speed is lower

it always lies along the normal.

it is bent away from the normal.

A straight glass rod appears to bend when placed in a beaker of water, as shown in the diagram below. What is the best explanation for this phenomenon?

Light is refracted as it crosses the air-water interface

The water is warmer than the air

Light travels faster in water than in air

Light is reflected at the air-water interface

What happens to the speed and frequency of a light ray when it passes from air into water?

The speed decreases and the frequency remains the same

The speed decreases and the frequency increases

The speed increases and the frequency increases

The speed increases and the frequency remains the same

Why would a wave change direction?

Because it went from one medium to another

Because it kept traveling through the same medium

When light waves move from passing through air to passing through a glass lens when happens to them?

They slow down and change direction

They speed up and change direction

They maintain the same speed and change direction

They maintain their same speed and direction

1) Refraction happens when light______

bends as it enters a new medium

bounces back when it hits a surface

It changes from a particle to a wave

Why would a wave change direction?

Because it went from one medium to another

Because it kept traveling through the same medium

Waves refract as they pass from one medium into another. Which best describes a beam of light moving from a less dense medium into a more dense medium?

Speed decreases. Wavelength decreases. Frequency remains constant.

Speed decreases. Wavelength increases. Frequency increases.

Speed decreases. Wavelength decreases. Frequency increases.

Speed decreases. Wavelength increases. Frequency decreases.

A student placed a pencil in a cup of water. The pencil appears broken because light-

always travels in a straight line

bends when it passes through water

makes the water in the glass evaporate

reflects the pencil on the water's surface

Why does the lower part of the child appear so much different in size from the upper part?

The light rays that travel through water and then into air are refracted.

The light rays that travel through water and then into air are enlarged.

The light rays that travel through air and then into water are reflected.

The light rays that travel through air and then into water are reduced.
