Light Waves Unit Test Review (Darr)

Front

What is a wave?

Back

A pattern that describes how energy is carried from one place to another.

Front

What is the formula to calculate wave speed?

Back

Wave speed = Frequency x Wavelength.

Front

If a wave has a frequency of 50 Hz and a wavelength of 10 m, what is its speed?

Back

500 m/s.

Front

What does light carry that can cause materials to change?

Back

Energy.

Front

What happens when a material allows light to pass through it?

Back

The material transmits the light and doesn't change.

Front

What is the definition of frequency in the context of waves?

Back

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

Front

What is wavelength?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa.

Front

What is reflection in terms of light waves?

Back

When light bounces off a surface.

Front

What is refraction?

Back

The bending of light as it passes from one medium to another.
