Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E). The spectrum can be ordered according to frequency or wavelength.
What are the components of electromagnetic waves?
Electromagnetic waves have two components: an oscillating electric field and a perpendicular, comoving magnetic field which oscillates at the same frequency, but with a phase shifted by 90°. They describe the movement of a packet of energy between two points.
What are the 3 main electromagnetic waves?
Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.
What are 3 facts about electromagnetic waves?
- Electromagnetic waves transmit energy.
- A trough is the lowest point of a wave and a crest is the highest point.
- Near infrared waves are used in remote controls.
- Far infrared waves are radiant heat.
- Gamma rays have the greatest energy.
What are 2 parts of an electromagnetic wave?
Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.
What are three characteristics of electromagnetic waves that can be measured?
Measuring electromagnetic radiation
Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency. Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters. Energy is measured in electron volts.
