Refraction and Diffraction Flashcard

Front

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?

Back

Glass is denser than water

Front

What type of stuff can be refracted?

Back

anything that travels in waves

Front

When does light refract?

Back

it Changes speed

Front

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

Back

The colors that make up white light refract at different angles

Front

Which of the following is the best example of diffraction?

Back

Your voice echoing back when you shout into a canyon

Front

Diffraction is useful in which of the following fields? Options: calculus, Anthropology, Astronomy

Back

Astronomy

Front

What's an easy way to create an interference pattern of waves?

Back

Toss two pebbles into the water close to each other; the waves from each pebble will interfere with the other.

Front

Blue light bends more than red light when it passes through glass. Thus blue light has a greater:

Back

Angle of refraction

Front

What is the main difference between refraction and diffraction?

Back

Refraction involves the bending of light; diffraction involves the bending and spreading of light, usually around an obstacle.
