Back 5

It is always upright and smaller.

Front 6

Light bending when it crosses between two mediums is called

Back 6

Refraction

Front 7

As light travels from one medium to another, the [BLANK] stays constant.

Front 13

The medium that is required to propagate an electromagnetic wave

Back 13

None of the above.

Front 14

An object in front of a lense produces a real image. What is true about this image?

Back 14

It is inverted

Front 15

Back 15

Figures 2 and 4

Front 16

If an object is placed less than the focal distance away from a converging lens, the image will be

Back 16

Larger, virtual, upright

Front 17

If an object is placed further away than the focal distance for a diverging lens, the image will be

Back 17

Virtual, smaller, upright.

Front 18

When an incidence ray of light strikes the surface of an object the ray can be

Back 18

Reflected, absorbed, scattered, and transmitted.

Front 19

If an object moves towards earth, the light emitted by the object is shifted

Back 19

Blue

Front 20

Different refraction for different colors is due to

Back 20

Speed of light in a medium, wavelengths of white light, angle of incidence, and frequency of white light

Front 21

The angle of incidence is shown by what letter in the figure?

Back 21

Front 22

Dense materials have what type of index of reflection? How will light move through this material?

Back 22

Higher, slower

Front 23

For a divergent lens, where will the focal point be?

Back 23

The back side of the lens.

Front 24

Total internal reflection can only happen when the speed of light is

Back 24

Less in the current material

Front 25

A light ray will refract the furthest from normal in a material:

Back 25

With a smaller n than the incident material.
