Study Notes
Electromagnetic Radiation
- Electromagnetic radiation is a form of energy that propagates through electromagnetic waves, which are created by the vibration of charged particles, such as electrons.
Characteristics of Electromagnetic Radiation
- Electromagnetic radiation has both electric and magnetic components that are perpendicular to each other and the direction of propagation.
- Electromagnetic radiation can travel through a vacuum, and its speed is always constant, approximately 3 x 10^8 meters per second (m/s) in a vacuum.
- The characteristics of electromagnetic radiation can be described by its frequency (ν), wavelength (λ), and speed (c), which are related by the equation c = λν.
Speed of Electromagnetic Wave
- The speed of an electromagnetic wave is calculated using the equation c = λν, where c is the speed, λ is the wavelength, and ν is the frequency of the wave.
Spectroscopy
- Spectroscopy deals with the interaction between matter and electromagnetic radiation, and it involves the measurement of the absorption or emission of radiation by atoms or molecules.
Energy in Photons
- The energy in the photons of electromagnetic radiation is calculated using the equation E = hν, where E is the energy, h is Planck's constant, and ν is the frequency of the radiation.
- The energy of the photons is directly proportional to the frequency of the radiation, and inversely proportional to the wavelength.
