The Nature of Waves Wave – a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium.

Medium Medium – a substance through which a wave can travel. (ANY solid, liquid, or gas). Any wave that needs a medium is called a Mechanical wave. (Ocean waves, sound wave, and earthquake)

Waves without a medium Electromagnetic waves – waves that do not need a medium. Include: visible light, microwaves, TV signals, radio waves, and X rays.

Types of waves There are three types of waves. Transverse waves Longitudinal waves Surface Waves

Transverse Waves Transverse waves – a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling. The wave travels forward, while the medium moves up and down. CREST CREST TROUGH TROUGH

Longitudinal Waves Longitudinal Wave – a wave in which the particles of the medium vibrate parallel to the direction of wave motion. Particles move back and forth, just like the wave does. Think of a spring.

Properties of Waves Amplitude – the maximum distance that the particles of a wave’s medium vibrate from their rest position. The larger the amplitude, the more energy the wave has. Amplitude WAVELENGTH REST Position WAVELENGTH

Which wave has a higher amplitude? Which wave has more Energy?

Wavelength Wavelength- the distance from any point on a wave to an identical point on the next wave. Shorter wavelength = more energy.

Frequency of a Wave Frequency – the number of waves produced in a given amount of time. Higher frequency = more energy Frequency is measured by counting how many waves pass by in a certain amount of time.
