The pictures shows what a student observed when he looked through a hand lens at a penny.
What happens to light passing through a hand lens that makes the image of the penny appear larger? The light is-
absorbed
reflected
refracted
stopped
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
Why does the lower part of the child appear so much different in size from the upper part?
The light rays that travel through water and then into air are refracted.
The light rays that travel through water and then into air are enlarged.
The light rays that travel through air and then into water are reflected.
The light rays that travel through air and then into water are reduced.
What do we call this tool that separates white light into the colors of the Visible Spectrum?
tuning fork
prism
microscope
graduated cylinder
Is a convex lens thicker or thinner in the middle?
Thicker
Thinner
When light waves move from passing through air to passing through a glass lens when happens to them?
They slow down and change direction
They speed up and change direction
They maintain the same speed and change direction
They maintain their same speed and direction

Reflection
Refraction
Diffraction
Dispersion
Why do objects appear bent when partially submerged in water?
Due to reflection of light
Due to refraction of light
Due to diffraction of light
Due to absorption of light
