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.
