Light is Waves

Which of the following IS NOT a behavior that light waves can undergo when they reach a boundary between two media?

• stopping at the edge of the boundary

• reflection off of the boundary

• transmission into the boundary

• refraction through the boundary

What particles make up light?

• Photons
• Neutrons
• Protons

Light behaves like both a particle and a ______.

• Mass
• Wave
• Current

Why does light refract?

• speeds up

• gets hot

• slows down

• gains energy

A slit of width a is used to observe a diffraction pattern on a screen at a distance L from the slit.If the width of the slit were doubled, the width of the central bright band would

• decrease by a factor of 4

• decrease by a factor of 2

• increase by a factor of 2

• increase by a factor of 4

This image is representing what wave interaction?

• Refraction
• Diffraction
• Reflection
• Interference

Two waves E and G are shown. The waves have the same speed.

Which statement is correct?

• Wave E has a greater amplitude than wave G.

• Wave E has a greater intensity than wave G.

• Wave E has a smaller frequency than wave G.

• Wave E has a smaller wavelength than wave G.

What is a general definition of wave interference?

• When a wave bounces off an object

• When more than on wave meet and interact in the same medium

• When a wave bends around a corner

• When a wave creates static

In a single slit diffraction experiment the width of the slit is reduced . What happens to the width of the central bright fringe in the resulting diffraction pattern

• Stays the same

• It becomes narrower

• it becomes wider

• the central bright fringe disappears

A single slit diffraction pattern is formed on a distant screen. Assuming the angles involved are small, by what factor will the width of the central bright spot on the screen change if the wavelength of the illuminating light is doubled?

• It will be cut to one -quarter its original size

• It will be cut in half

• It will double

• It will become four times as large
