What is Frequency of radiation with wavelength 436 NM?

The frequency of radiation with a wavelength of 436 nm can be calculated using the formula: frequency = speed of light / wavelength. Plugging in the values (speed of light = 3.00 x 10^8 m/s and wavelength = 436 x 10^-9 m), the frequency is approximately 6.88 x 10^14 Hz.
