Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by oscillations or vibrations.

Front

What are the two main types of waves?

Back

Mechanical waves (require a medium, e.g., sound waves) and electromagnetic waves (do not require a medium, e.g., light waves).

Front

What is wavelength?

Back

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

Front

What is amplitude?

Back

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

Front

What is frequency?

Back

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

Front

What is a crest?

Back

A crest is the highest point of a wave.

Front

What is a trough?

Back

A trough is the lowest point of a wave.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is a medium in the context of waves?

Back

A medium is the substance through which a wave travels, such as air, water, or solid materials.

Front

Why can't sound travel in outer space?

Back

Sound cannot travel in outer space because there is no medium (air or other substance) for the sound waves to travel through.
