how does diffraction work
it goes through water and air
is a beam of light stopping at a wall
it bounces off of light
is the bending of light as it passes around the edge of an object
- 2. Multiple Choice
witch picture is diffraction
- 3. Multiple Choice
A beam of light bends when it passes from air into water, and more when it passes from water into glass. What can you conclude from this fact?
Air is denser than glass
Water is denser than glass
Glass is denser than water
Air is denser than water
- 4. Multiple ChoiceWhat type of stuff can be refracted? Choose the best answer.Lightsoundheatanything that travels in waves
- 5. Multiple ChoiceLight refracts when:it Changes speedit changes from a particle to a waveits density changesit encounters a solid object
- 6. Multiple ChoiceWhat is the main difference between refraction and diffraction?refraction is a phenomenon that affects light; diffraction is a phenomenon that affects soundrefraction involves the bending of light; diffraction involves the bending and spreading of light, usually around an obstacle
