Electromagnetic Waves

Electromagnetic Waves Waves that consist of electric and magnetic fields that vibrate at right angles to one another. Radiation- the transfer of energy as electromagnetic waves. Travel without a medium

Electromagnetic Spectrum All of the frequencies of wavelengths of electromagnetic radiation.

Visible Light A very narrow range of wavelengths and frequencies in the electromagnetic spectrum that human can see.

Electromagnetic Spectrum Activity You and your partner are going to create your own diagram of the electromagnetic spectrum on a sentence strip. Draw a line with decreasing wavelength and increasing frequency. For each classification of electromagnetic waves: describe the type of wave Specify the range of wavelengths Draw a picture. Use pages 636-642 to gather information.
