S2 Review 4 - waves

Front

What happens to the wavelength of a wave as its frequency decreases?

Back

The wavelength increases.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed = frequency × wavelength.

Front

Define a transverse wave.

Back

A wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is the amplitude of a wave?

Back

The maximum displacement of points on a wave from its rest position.

Front

How does the amplitude affect the energy of a wave?

Back

Higher amplitude means more energy.

Front

What is the period of a wave?

Back

The time it takes for one complete cycle of the wave to pass a given point.

Front

What is the relationship between frequency and period?

Back

Frequency is the reciprocal of the period (Frequency = 1/Period).

Front

Describe the motion of particles in a longitudinal wave.

Back

Particles move parallel to the direction of the wave's travel.

Front

What is a wavefront?

Back

An imaginary line that connects all points of a wave that are in phase.

Front

What is the difference between constructive and destructive interference?

Back

Constructive interference occurs when waves combine to make a larger wave; destructive interference occurs when waves combine to make a smaller wave.
