Wavelength

The wavelength of a wave is an extremely important and unique aspect because it helps to determine how that wave is perceived, as we will soon see. Wavelength is measured from crest to crest (or trough to trough) on a wave.

Aspects of Waves

There are certain aspects of waves (both transverse and longitudinal) which affect the way in which they are perceived. These are wavelength, amplitude, and frequency.

Longitudinal Waves

For longitudinal waves, the direction of energy transfer is the same as the movement of the particles. Particles in such a wave hit one another (compress) in order to transfer energy on to the next particles.

Types of Waves

There are two main types of waves: longitudinal and transverse. Sound waves are longitudinal (compression) waves, and light waves are transverse. These types of waves affect how we perceive the world in our everyday lives

Sight and Sound Intro.

Both light and sound travel through waves; however, the two types of waves through which they travel are extremely different. The differences between these waves are what allow for sight and sound.
