Georgia Standards S8P4A: Properties of Electromagnetic and Mechanical Waves.

Mechanical Waves

Waves that require a medium to travel through, such as sound.

Electromagnetic Waves

Waves that can travel through the vacuum of space without the need for matter.

Wavelength

The distance between consecutive peaks of a wave.

Amplitude

The height of a wave, related to the volume in sound and brightness in light.

Frequency

The number of waves that pass a given point in a specific amount of time, determining the pitch of a sound.

Longitudinal Waves

Waves where the particle movement is parallel to the direction of the wave, exemplified by compressions and rarefactions using a Slinky.

Transverse Waves

Waves where the particle movement is perpendicular to the direction of the wave, characterized by crests and troughs.

Crest

The highest point of a wave.

Trough

The lowest point of a wave.

Sound Waves

A type of mechanical wave that travels through a medium, such as air, water or solids.

Vacuum of Space

An area in space devoid of matter, allowing electromagnetic waves to travel.

Compression

A point in a longitudinal wave where particles are closest together.

Rarefaction

A point in a longitudinal wave where particles are spread apart.

Wave Properties

Characteristics that define waves, including wavelength, amplitude, and frequency.

Brightness in Light

The visual intensity of light related to the amplitude of electromagnetic waves.

Pitch of Sound

The perceived frequency of a sound wave.

Medium

Substance through which mechanical waves travel, such as air or water.

Wave Types

Categories of waves, including mechanical and electromagnetic waves.

Daily Life Waves

The presence and effects of waves in everyday experiences, such as light and sound.

Wave Measurement

Methods of quantifying properties of waves such as wavelength, frequency, and amplitude.

Sonic Waves

Waves produced by sound that require a medium to propagate.
