1 The Electromagnetic Spectrum

2 Energy and Waves The energy that comes from the sun is called electromagnetic radiation. This energy is carried by several waves with different wavelengths and frequencies. Long wavelength = Low frequency Short wavelength = High frequency Higher frequency = more energy



5 Types of Waves Radio Waves – radio broadcasts Microwaves – cell phones
Infrared rays – heat lamps Visible light – what we see Ultraviolet rays – vitamin D X-rays – view bones and teeth Gamma rays – treat cancer Video


7 Visible Light Visible, white light includes all colors of the rainbow.
ROYGBIV = red, orange, yellow, green, blue, indigo, violet. The color of an object that we see is the color of light reflected. All other colors are absorbed. Video


9 Vocabulary Wavelength – the distance between the crest (top) of one wave and the crest of the next. Frequency – the number of waves that pass a given point in a certain amount of time.
