Wave Reflection, Absorption, and Transmittance

Front

What are the properties of waves that determine color?

Back

Wavelength and frequency.

Front

What is the height of the wave from its resting point called?

Back

Amplitude.

Front

How does the amplitude of a light wave affect its brightness?

Back

A higher amplitude light wave will be brighter, and a lower amplitude light wave will be dimmer.

Front

What is the unit of measurement for frequency?

Back

Hertz.

Front

What do waves move instead of matter?

Back

Energy.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

The number of waves that pass a point in one second, measured in Hertz.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases, and vice versa.

Front

What happens to light when it is absorbed by a surface?

Back

The energy of the light is taken in by the surface, often converting to heat.

Front

What is wave reflection?

Back

The bouncing back of a wave when it hits a barrier.
