Electromagnetic Waves

Electromagnetic Waves

They transfer energy from one place to another without carrying any matter (stuff)

Wavelength: Distance from one peak to the next

Frequency: how many complete waves there are per second (in Hz)

Amplitude: The height of the wave

All the types of electromagnetic waves travel at the same speed in a vacuum

Electromagnetic waves with high frequency have low wavelengths

Wave speed (m/s) = Frequency (Hz) X Wavelength (m)

Radiation can be absorbed, reflected or transmitted...

Transmitted: Just passes through the substance (e.g. light passing through glass)

Reflected: Bounces back (e.g. light reflecting off a mirror)

Absorbed:…
