A person observes a fish in a lake. The position of the fish is shown.

Which statement best explains why the observed fish appears to be closer to the surface than the actual fish?

• When light travels from water into air, the light changes direction.

• the light bounces off of the water and creates a reflected image of the fish

• When white light passes through the surface of the water, the light separates into colors.

• The light enters the water and exits the water at the same angle.

A student is looking directly at a lit nightlight through two different cardboard tubes as shown.

Through which tube, if any will the light be seen and why?

• The bent tube only because the light bounces off the sides of the tube and travels through the tube to the student's eye

• The straight tube only because the light travels in a straight line directly to the student's eye

• Both tubes because light travels equally well along straight and curved paths

• Neither tube because both tubes absorb all of the light

The student is observing part of a plant with a microscope.

Which statement describes a behavior of light in the microscope?

• Light travels through the microscope lens without changing direction.

• Moving in straight lines causes light to increase in brightness.

• Light refracts through the lens of the microscope.

• Moving in straight lines keeps light from reflecting.

For a class demonstration a student turned off the lights in the classroom. The student then shined light from a flashlight through a hole in a piece of cardboard. The class saw the narrow beam of light continue until another student placed a mirror in the light's path.

The light did not continue past the mirror because ---

• light cannot travel very far

• the mirror absorbed all the light

• the light was refracted back to the light source

• light travels in a straight line and cannot go around objects

A thin beam of light is shown in this picture.

What does the picture demonstrate about light?

• Light and its reflections travel in straight lines.

• Light cannot reflect from more than one surface.

• Light that goes through water cannot travel in straight lines.

• Light can travel in a circular path.

A student conducts an investigation by shining a flashlight toward a flat mirror. The student changes the angle of the mirror and observes the path of the reflected light.

As the mirror changes direction, the light reaching the mirror can reach the ceiling because the light ---

• travels in straight lines and reflects from the surface of the mirror

• refracts in the glass of the mirror and is spread out all over the room

• enters the mirror and changes direction when it is refracted by the back of the mirror

• travels through air and does not change it direction in air

Some students are feeding a crab in an aquarium. They use tongs to place the food directly in front of the crab.

The students look through the side of the aquarium. They notice that the image of tongs appears to break as the tongs enter the water.

Which property of light are the students observing in this situation?

• Light can be refracted and separated into different colors as it moves from air to a different medium.

• Light is refracted as it moves from one medium to another medium.

• Light travels in a straight line and can be reflected off the surface of water.

• Light is absorbed by water and reflected off glass.
