Part of a pencil that is placed in a glass of water appears bent in relation to the part of the pencil that extends out of the water. What is this phenomenon called?

• Interference

• Refraction

• Diffraction

• Reflection

Refraction is the bending of a wave disturbance as it passes at an angle from one __________ into another.

• Glass

• Medium

• Area

• Boundary

The __________ of light can change when light is refracted because the medium changes.

• Frequency

• Color

• Speed

• transparency

Light is not refracted when it is

• traveling from air into a glass of water at an angle of 35° to the normal.

• traveling from water into air at an angle of 35° to the normal.

• striking a wood surface at an angle of 75°.

• traveling from air into a diamond at an angle of 45°

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

• it is bent toward the normal to the surface.

• it always lies along the normal to the surface.

• it is unaffected.

• it is bent away from the normal to the surface.

What type of image is formed when rays of light actually intersect?

• real

• curved

• virtual

• projected

What type of image does a converging lens produce?

• real

• virtual

• real or virtual

• none of the above

In what direction does a parallel ray from an object proceed after passing through a diverging lens?

• The ray passes through the center of curvature, C.

• The ray continues parallel to the principal axis.

• The ray passes through the center of the lens.

• The ray is directed away from the focal point, F.

How many focal points and focal lengths do converging and diverging lenses have?

• two, one

• one, one

• one, two

• two, two
