CFA: Waves Behavior Review

Front

What is a wave trough?

Back

A wave trough is the lowest point of a wave, where the wave's displacement is at its minimum.

Front

What is refraction in wave behavior?

Back

Refraction is the bending of a wave as it passes from one medium to another, caused by a change in its speed.

Front

What type of wave is visible light?

Back

Visible light is an electromagnetic wave that can be seen by the human eye.

Front

What do all waves carry?

Back

All waves carry energy.

Front

What happens to a light ray when it strikes a reflective surface?

Back

When a light ray strikes a reflective surface, it bounces back, a process known as reflection.

Front

What is the definition of a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its amplitude, wavelength, and frequency.

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, the particle displacement is perpendicular to the direction of wave propagation, while in a longitudinal wave, the particle displacement is parallel to the direction of wave propagation.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second).

Front

What is the principle of superposition in wave behavior?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual wave displacements.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.
