Question

The ratio between the wave numbers of spectral lines of balmer series of hydrogen having the least and the highest wavelength values is

Answer 1

Explanation:

The ratio between the wave numbers of spectral lines of balmer series of hydrogen having the least and the highest wavelength values is For hydrogen (Z = 1) this transition results in a photon of wavelength 656 nm (red).Hooe this would be helpful.

Answer 2

The ratio between the wave numbers of spectral lines of balmer series of hydrogen having the least and the highest wavelength values is 9:5

Explanation:

• In the Balmer series for  Z=1 the hydrogen atom will have the highest wave length will be the first line and the least wave length will be the limiting line.
• It is the series which is known as balmer series of a spectral emission line of hydrogen atom
• This is a result of electron transitions from higher levels down to the lower energy level with n=2 as a principal quantum number.
• On calculating the value of ratio with the help of n we get the value as 9:5.
