Ultraviolet (UV) light is a form of electromagnetic radiation with a frequency higher than that of visible light. The specific frequency range for ultraviolet light is typically defined as wavelengths between approximately 10 nanometers (nm) and 400 nm.
To calculate the frequency of a wave, we can use the equation:
c = λ * f
Where: c is the speed of light (approximately 3.00 x 10^8 m/s), λ is the wavelength of the wave, and f is the frequency of the wave.
Rearranging the equation to solve for frequency:
f = c / λ
For ultraviolet light, let's consider a commonly used wavelength of 400 nm.
λ = 400 nm = 400 x 10^-9 m (converting from nanometers to meters)
Substituting the values into the equation:
f = (3.00 x 10^8 m/s) / (400 x 10^-9 m)
Simplifying the expression:
f ≈ 7.5 x 10^14 Hz
Therefore, ultraviolet light has a frequency of approximately 7.5 x 10^14 hertz (Hz).
