Electromagnetic Radiation
- Energy is being transmitted from one place to another by light
- Many different kinds
- The wavelength is the distance between two consecutive wave peaks
- The frequency indicates how many wave peaks pass a certain point per given time period
- Light travels in waves
- Another way to think of a beam of light traveling through space is as a stream of tiny packets of energy called photons
- Different wavelengths of electromagnetic radiation carry different amounts of energy
- The photons that correspond to red light carry less energy than the photons that correspond to blue light
- The longer the wavelength of light, the lower the energy of tis photons
