Wavelength is an important property of a wave which denotes the distance between successive crests or troughs of a wave. It is usually denoted by the letter λ and can be expressed in meters or nanometers.
The 'H' spectrum consists of several series of lines appearing in the different regions of the electromagnetic spectrum. The Lyman series of lines occurs in the UV-region and Balmer series of lines occurs in the visible region.
It was the Balmer series named after the scientist J.J Balmer. It has 4 prominent lines, designated H α ,   H β ,   H υ and H δ in the red, blue-green, blue and violet regions respectively.
The shortest wavelength in the Balmer series is 364.5 nm. Hence among the given options, the correct answer is a -364.5 nm .
