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

What is the main difference between refraction and diffraction?

• refraction is a phenomenon that affects light; diffraction is a phenomenon that affects sound
• refraction involves the bending of light; diffraction involves the bending and spreading of light, usually around an obstacle

The bending of light rounds the corners of an obstacle is called

• Diffraction

• Interference

• Polarization

• Refraction
