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.

What is reflection?

• Reflection is the bouncing  of light off the surface that it strikes on.

• Reflection is the absorbing of light off the surface that it strikes on.

• Reflection is the bending of light off the surface that it strikes on.

• Reflection is the scattering of light off the surface that it strikes on.

• Refraction

• Reflection

Refraction is when light__________.

• Is bounced by an object or material.

• Changes speed as it travels in different materials which causes bending.

• When light speeds up to over 300,000 km/s
