For wavelength of visible radiation of hydrogen spectrum Balmer gave an equation as = ( km ^2 ) ( m ^2-4 ) , where m is the integer value. The value of k in terms of Rydberg's constant R is

Options

  1. AR 4
  2. B4 R
  3. CR
  4. D4 R

Correct answer

B. 4 R

Step-by-step solution

Wavelength of visible radiation in Balmer series is given by, aligned & 1 =R ( 1 4 - 1 m^2 ) for m 2 & = 4 R m^2 m^2-4 = k m^2 m^2-4 aligned k= 4 R
