What is a wave?

Back

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

Front

What are the main types of waves?

Back

The main types of waves are mechanical waves (require a medium, e.g., sound waves) and electromagnetic waves (do not require a medium, e.g., light waves).

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 frequency?

Back

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

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

How does energy relate to wavelength and frequency?

Back

Energy is directly proportional to frequency and inversely proportional to wavelength; higher frequency means higher energy, while longer wavelength means lower energy.

Front

What color of visible light has the highest energy?

Back

Violet light has the highest energy among visible light colors.

Front

What happens to wavelength when frequency increases?

Back

When frequency increases, wavelength decreases.

Front

What is the relationship between amplitude and sound volume?

Back

Higher amplitude in sound waves corresponds to a louder sound, while lower amplitude corresponds to a softer sound.

Front

What is pitch in relation to sound waves?

Back

Pitch is the perceived frequency of a sound; higher frequency results in a higher pitch.
