S8P4 Waves Review 2

Front

What is a wavelength?

Back

The distance between two consecutive crests or troughs in a wave.

Front

How many wavelengths are in a wave with 3 crests?

Back

3.0 wavelengths.

Front

What is refraction?

Back

The bending of a wave as it passes from one medium to another, changing its speed.

Front

Which color of visible light has the longest wavelength?

Back

Red.

Front

Which color of visible light has the shortest wavelength?

Back

Violet.

Front

What happens to the energy of a wave as its frequency increases?

Back

The energy of the wave increases.

Front

What is the relationship between wavelength and frequency?

Back

They are inversely related; as wavelength increases, frequency decreases.

Front

What is the order of visible light colors from longest to shortest wavelength?

Back

Red, Orange, Yellow, Green, Blue, Violet.
