What is amplitude in relation to waves?

Back

Amplitude is the height of a wave from its rest position, indicating the energy level of the wave. A higher amplitude means more energy and a brighter light wave.

Front

What are the properties of waves?

Back

The properties of waves include amplitude, wavelength, and frequency.

Front

What is the difference between sound waves and light waves?

Back

Sound waves need matter (medium) to travel, while light waves do not require a medium and can travel through a vacuum.

Front

What is a wave?

Back

A wave is a repeating pattern of motion that transfers energy from one place to another.

Front

What do waves move?

Back

Waves move energy, not matter.

Front

Define 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 frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in a given period of time, usually measured in Hertz (Hz).

Front

How does amplitude affect the brightness of light?

Back

A higher amplitude light wave will appear brighter, while a lower amplitude light wave will appear dimmer.

Front

What happens to sound waves in a vacuum?

Back

Sound waves cannot travel in a vacuum because they require a medium (like air, water, or solid materials) to propagate.

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.
