How does light behave as it enters these mediums?

• continue its path as straight line.
• bends toward the normal
• bends away from the normal

• reflection
• reconstroction
• retraction

When light passes at an angle to the normal from one medium into another in which its speed is higher

• it is bent toward the normal.

• it always lies along the normal.

• it is unaffected.

• it is bent away from the normal.

If all other variables are held constant, what happens to the angle of refraction if the angle of incidence increases?

• the angle of refraction stays the same

• the angle of refraction decreases

• the angle of refraction increases

• cannot be determined from the information provided

A student placed a pencil in a cup of water. The pencil appears broken because light

• always travels in a straight line.

• bends when it passes through water.

• makes the water in the glass evaporate.

• reflects the pencil on the water's surface.
