Frequency is the number of waves that pass a fixed point in a given unit of time, typically measured in hertz (Hz). It determines the energy and type of light in the electromagnetic spectrum.
5 Must Know Facts For Your Next Test
Higher frequency light has more energy than lower frequency light.
Frequency is inversely proportional to wavelength; as frequency increases, wavelength decreases.
Visible light spectrum ranges from approximately 400 THz to 789 THz.
Ultraviolet (UV) light has a higher frequency than visible light, which allows it to penetrate cells and cause damage.
Microorganisms can be visualized using different frequencies of light, including UV and infrared.
