What is the wavelength in nanometers?

The Visible Light Spectrum – Wavelengths of Colors NOTE: Wavelengths of visible light are measured in nanometers (nm). A nanometer is a unit of length equal to one billionth of a meter.

What is the formula to calculate wavelength?

The wavelength is calculated from the wave speed and frequency by λ = wave speed/frequency, or λ = v / f.

How do you find the number of spectral lines in hydrogen spectrum?

Possible spectral lines= (n2-n1)(n2-n1+1)/2 this is the possible numbers.
