Properties of Waves

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What happens to light waves when they hit a mirror?

Back

The light waves bounce back, a phenomenon known as reflection.

Front

What is a wave crest?

Back

A wave crest is the highest point of a wave.

Front

What is a wave trough?

Back

A wave trough is the lowest point of a wave.

Front

What is the relationship between frequency and wavelength?

Back

If a wave has a greater frequency, its wavelength decreases.

Front

What is reflection in terms of waves?

Back

Reflection is when waves bounce off a surface, such as light bouncing off a mirror.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another.

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.
