LESSON 1: WAVES

LESSON 1: WAVES

ELECTROMAGNETIC SPECTRUM

Topic: Describe a wave and identify parts of the Electromagnetic Spectrum from longest to shortest.

Describe the properties of waves.

Wave – a disturbance that transfers energy through matter and space.

Describe the properties of waves.

Two properties of waves:

1. Wavelength – the distance between one crest of a wave to the next crest
2. Frequency – the number of wavelengths that pass a point in a given amount of time.

Describe the properties of waves.

Frequency and wavelength are related. Short wavelength – high frequency

Long wavelength – low frequency

Explain electromagnetic energy and

the electromagnetic spectrum.

Energy that travels through space in the form of waves is called electromagnetic energy. This energy is a type of radiant energy.

Explain electromagnetic energy and

the electromagnetic spectrum.

All electromagnetic waves travel at the same speed – about 300,000 km / sec. (The speed of light !)

Explain electromagnetic energy and

the electromagnetic spectrum.

Waves from longest wavelength to shortest: Radio Waves, Microwaves, Infrared Waves, Visible light, Ultraviolet radiation, X-rays, Gamma rays
