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.
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.
Why does the straw appear to be bent?
light is reflected
light is absorbed
light is turned
light is refracted
What is the angle of reflection equal to?
The angle of refraction
The angle of incidence
The angle of absorption
The angle of light
When a light ray enters a more dense medium it will...
speed up
slow down
not change speed
Angle 1 is called the angle of (a) .
Angle 2 is called the angle of (a) .
What is a plane mirror?
A curved mirror
A flat mirror
A round mirror
A square mirror
What is the law of reflection?
Angle of incidence = angle of refraction
Angel of incidence = angel of reflection
Angle of reflection > angle of refraction
Angle of incidence = angle of refraction
How will a light ray bend when it goes from a more dense to a less dense medium?
Towards the normal
90 degrees
45 degrees
Away from the normal
