Questions and Answers

What characterizes a wave in physics?

A wave can't have different forms or types.

Study Notes

Waves and Wavelengths

Waves transfer energy, not matter, from one place to another
Examples of waves include ocean swells, sunlight, and sound
Seismic waves (earthquakes), light waves (distant stars), and sound waves are all examples of different types of waves
All waves, regardless of type, have energy in common

What is a Wave?

A wave is a disturbance that transfers energy
Energy, not matter, moves with the wave
The medium through which a wave travels moves back and forth, not along the wave
Examples of mediums include water, rope, and air

How Waves Work

Imagine shaking one end of a rope
Upward movement creates a high point or crest
Downward movement creates a low point or trough
The rope itself doesn't move along the wave, only the energy moves with it
Water waves, similar to a rope, have crests and troughs due to the water's up-and-down motion
The energy moves, while the water returns to its original position

Wavelength

Wavelength is the distance between two corresponding points on a wave
Usually measured between two crests or two troughs
Different waves have different wavelengths
Wavelength and frequency relate to the amount of energy a wave has
Short waves have more energy
Long waves have less energy

Frequency

Describes how many waves pass a point per second
Measured in Hertz (Hz)
Higher frequency waves have more energy
Examples of waves include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays
Each wave has a different frequency and wavelength, and these types of waves make up the electromagnetic spectrum

Electromagnetic Spectrum

A range of all types of electromagnetic radiation
Ordered by frequency and wavelength
Radio waves have the longest wavelengths and lowest frequencies (lowest energy)
Gamma rays have the shortest wavelengths and highest frequencies (highest energy)
