REFRACTION and REFLECTION

How does light behave as it enters these mediums?

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

What is this called?

• refraction
• 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.

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.

We can see objects because of_______

• reflection
• refraction
• transmission
• diffraction

The velocity of light in vacuum is _______ m/s

• 3x10⁸
• 3x10¹²
• 3x10⁶
• 3x10¹⁰

Swimming pools and the ocean look shallower than they really are due to:

• reflection 
• dispersion
• refraction
• total internal reflection

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.

The fact the two angles are the same is an example of....

• Refraction
• Angle of Incidence
• Law of reflection
• Magnification

The image formed in a flat mirror is

• larger than the object and farther away.
• reduced and closer to the mirror.
• a real image of the object.
• equal to the height and distance of the object.
