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

When a wave moves around a barrier or though an opening it is known as what?

• Diffraction
• Refraction
• Rarefaction
• Destruction

Why does white light from the sun form a colorful rainbow when it passes through water droplets in the atmosphere?

• The droplets of water in the air have different densities

• Different-sized water droplets refract white light at different angles

• The colors that make up white light refract at different angles

• White light diffracts when it encounters water

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.

• Refraction usually happens in the atmosphere; diffraction usually happens closer to the earth's surface.

• Refraction involves changes to the density of light; diffraction involves changes to the speed of light.
