What is the frequency range of visible light in Hz?

Visible light has frequencies ranging from 4*1014 Hz to 8*1014 Hz (400 THz to 800 THz) and wavelengths from 3.8*10-7 m to 7.5*10-7 m (380 nm to 750 nm). Red light has the lowest frequency (longest wavelength) and violet light has the highest frequency (shortest wavelength) of visible light.

Similarly, what is the frequency of infrared waves in Hertz?

Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Below infrared is the microwave portion of the electromagnetic spectrum.

What is the frequency of microwaves in Hz?
