Study Notes
Electromagnetic Radiation
- The distance traveled by one complete wave cycle of electromagnetic radiation is measured in wavelengths.
Spectrum of Radiant Energy
- Radiant energy is characterized in terms of a spectrum, which is a range of frequencies and wavelengths.
Types of Light
- Gamma rays have very short wavelengths.
Wavelength and Energy
- There is an inverse relationship between wavelength and energy in light: as wavelength decreases, energy increases, and vice versa.
Properties of Electromagnetic Radiation
- Electromagnetic radiation exhibits both wave-like and particle-like properties, characterized by its dual nature, also known as wave-particle duality.
