Guided Notes

3 key concepts

  • 1

    Light is a form of energy that travels in waves, and we call it electromagnetic radiation.

  • 2

    The energy of light is related to its wavelength, where shorter wavelengths have more energy and are perceived as "bluer" colors.

  • 3

    By analyzing the light from distant objects using spectroscopy, we can determine their temperature, density, motion, and chemical composition.
