Waves Review PS

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points of a wave that are in phase, such as crest to crest or trough to trough.

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa, when the speed of the wave is constant.

Front

What is the formula for wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).

Front

What type of wave is sound?

Back

Sound is a longitudinal wave, meaning the particles of the medium move parallel to the direction of the wave.

Front

What is an electromagnetic wave?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium, such as light and radio waves.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What happens to sound waves as they travel through different mediums?

Back

Sound waves travel faster in solids than in liquids, and faster in liquids than in gases due to the density and elasticity of the medium.

Front

What is a microwave oven?

Back

A microwave oven uses low energy electromagnetic waves to heat food by making water molecules vibrate faster.
