Reflection and Refraction Review

Index of Refraction

1 on the index is equal to no bending at all....light travels straight through a vacuum.
The higher the index of refraction the more the light bends

Types of lenses

Concave Lens
Convex Lens

Concave Lens

"caves in" on either side of lens
thinner in the middle than at the edges
The parallel light rays enter and then exit angled away from one another never meeting at a focal point
Like a Convex Mirror it produces only virtual images

Convex Lens

Thicker in the center than the edges
As parallel light rays enter the lens they exit at an angle so they meet at a focal point
If the object is between the focal point and the lens then a virtual image is produced
If the object is beyond the focal point then a real image is produced.

Multiple Choice

Light refracts when:

It changes speed

It changes from a particle to a wave

Its density changes

It encounters a solid object

Multiple Choice

Why does the straw appear to be bent?

light is reflected

light is absorbed

light is turned

light is refracted

Multiple Choice

What do we call a material that light can travel through?

air

water

medium

pathway

Multiple Choice

The illustration shows a light ray striking an object.
In the illustration, the light ray striking the object is-

absorbed

stopped

reflected

refracted

Multiple Choice

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.

Multiple Choice

What is the angle of reflection equal to?

The angle of refraction

The angle of incidence

The angle of absorption

The angle of light

Multiple Choice

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.

Multiple Choice

What is the angle of incidence?

The angle at which light bends in water.

The angle at which light hits a surface.

The angle at which light is absorbed by an object.

The angle at which light bounces off a surface.

Multiple Choice

According to the Law of reflection, a light ray striking a mirror

continues moving through the mirror in the same direction

moves into the mirror at a slightly different angle

bounces off the mirror toward the direction it came from

bounces off the mirror at the same angle it hits.

Multiple Choice

What is the angle of reflection (θ_r) in the image?

56^o

90^o

124^o

34^o

Multiple Choice

Light bending as it passes through a rain drop is an example of...

Refraction

Reflection

Multiple Choice

A beam of light bends when it passes from air into water, and more when it passes from water into glass. What can you conclude from this fact?

Air is denser than glass

Water is denser than glass

Glass is denser than water

Air is denser than water

Multiple Choice

A light ray is incident from water to air. Which of the refracted rays is correct?

Multiple Choice

Density is...

the amount of mass in an object

the amount of space an object takes up

the amount of mass in a given space

the weight of an object

Multiple Choice

The line 90 degress through the refracting or reflecting surface is called?

Medium

Normal

Incidence

Reflection

Multiple Choice

The incident ray is the light ray leaving the light source. The angle of ______________ correlates with the incident ray.

Incidence

Reflection

Refraction

Normal

Multiple Choice

Objects that reflect well are

Matte surfaces

Smooth, shiny surfaces

Dark coloured surfaces

Medium coloured surfaces

Multiple Choice

The law of reflection states that

Angle of incidence = Angle of reflection

Angle of incidence = Angle of incidence

Angle of reflection = Angle of translucence

Angle of reflection = Angle of reflection

135 degrees

Multiple Choice

Refraction is

The bending of light as it passes through the one substance at an angle

A light beam shone in one end of an optical fibre and totally internally reflected at the other end

The bending of light as it passes from one substance to another at an angle

A type of convex object used in everyday life
