Light

Question 1

On a normal plane mirror, compare the values of the angle of incidence and reflection:

Answer 1

angle of incidence= angle of reflection

Question 2

List the components you need to label/ include when you draw a diagram of a light beam reflecting off of a plane mirror:

Answer 2

-light ray (arrow)
-normal (90° from the surface)
-angle of incidence and reflection labeled

Question 3

Whats the difference between a real and virtual image?

Answer 3

A virtual image is an image that cannot be projected onto a screen, whereas a real image can.

Question 4

Describe and explain the pathway of a light ray as it passes through a glass prism:

Answer 4

when the light ray enters the glass prism from the air, since glass is denser than the air, the velocity of the light ray would decrease and bend towards the normal. as it leaves the prism, the velocity increase as it enter into a less dense medium, therefore bend away from the normal.

Question 5

What are the two types of lenses?

Answer 5

-concave )(
-convex ()

Question 6

What do concave lenses do to light rays?

Answer 6

diverge

Question 7

What do convex lenses do to light rays?

Answer 7

converge
