Why does the straw appear to be bent?
light is reflected
light is absorbed
light is turned
light is refracted
Why doesn’t the surface of a wooden boat reflect light as the surface of water does?
Because the boat's surface is rough and absorbs more light.
Because the surface of the boat is red, not blue.
Because the boat is not a natural object like the water is.
Because the boat is on top of the water's surface.

Diagram shows a phenomenon occurs when the spotlight is directed onto a mirror surface. What is the principle of light shown in the situation?
Light travels in a straight line
Refraction of light

If the angle of incidence in the diagram is 50 degrees, which statement is true?
The angle of reflection is 40 degrees because is is measured from the normal line, which is 90 degrees
The angle of reflection is 50 degrees because it is equal to the angle of incidence.
The angle of reflection is 60 degrees, because it is greater than the angle of incidence.
The angle of refraction is 50 degrees, because it is equal to the angle of incidence.
