Why does the straw appear to be bent?
light is reflected
light is absorbed
light is turned
light is refracted
In the illustration, the light ray striking the object is-
What might explain why light travels in a straight line?
If there is nothing to interfere with light waves, they should travel in a straight line.
Light waves will always travel in a straight line, even if they come into contact with another object.
Light waves don't travel in a straight line.
Light waves travel in a straight line because sound waves travel in a straight line.
___________ travels in a straight line until something changes its path
Medium
Refract
Reflect
Light
What is happening in this picture?
Reflection
Refraction
What is happening in this picture?
Reflection
Refraction
What happens to light passing through a hand lens that makes the image of the penny appear larger? The light is-
Which object DOES NOT reflect light?
a black brick
a mirror
a lake
aluminum foil
Which is a situation that demonstrates light bending as it travels from one medium to another?
When light hits a shiny surface
When light passes through a prism
When light hits a black-colored surface
When light passes through empty space
What is the difference between refraction and reflection?
Light bends when it is reflected and bounces off when it is refracted.
Light bounces off when it is reflected and bends when it is refracted.
Light travels in curved lines when it is reflected and straight lines when it is refracted.
When light is refracted, it no longer travels.
What happens when light strikes a dark, heavy object?
Light is refracted.
The light moves quickly through the medium.
Light energy is absorbed.
light does not strike dark objects.
The diagram shows a fish being viewed from above the water. The fish appears to be closer to the surface than it really is. What causes this difference? (5.6C)
Light is reflected.
Light is refracted.
Light is focused.
Light is blocked.
The diagram shows a periscope used to see objects that are behind or under a barrier. What makes it possible to see an object when looking through a periscope? The periscope –
separates the light into different colors
absorbs the light rays passing through it
magnifies small objects so they can be seen
contains mirrors that reflect the object

When light travels through air into a prism, it bends and separates into many colors. Which term describes how the light bends?
The light is absorbed by the prism.
The light is reflected by the prism.

Scientists use telescopes to make distant objects appear closer. Some parts of a telescope are shown below. Which of the following best describes how the objective lens of this telescope helps a scientist observe the moon?
The objective lens produces light.
The objective lens blocks light.
The objective lens reflects light.
The objective lens refracts light.
The picture shows how a light ray behaves with two different types of materials. Which table best describes the behavior of the light ray as it encounters the materials?
M1: The light ray is scattered in all directions.
M2: The light ray is refracted.
M1: The light ray is absorbed.
M2: The light ray is reflected.
M1: The light ray is transmitted.
M2: The light ray is refracted.
M1: The light ray is refracted.
M2: The light ray is reflected.
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.
