Study Notes
- Electromagnetic radiation is a type of energy that is odorless and tasteless, but is essential for our modern world.
- The electromagnetic spectrum ranges from gamma rays to radio waves, with each type of wave having different wavelengths and frequencies.
- Electromagnetic waves are similar to ocean waves in that they transmit energy, but they can travel through the vacuum of space at the speed of light.
- The visible light region of the spectrum, with wavelengths from 400 to 700 nanometers, is what our eyes are tuned to detect.
- Different objects interact with electromagnetic waves in different ways, and scientists can study these interactions using spectral signatures to determine properties such as composition and temperature.
