Answer #1

Actually ,

Rydberg's constant = 109678 cm^-1

The given frequency = 3.02 x 10¹⁵ s^-1

frequency = Velocity of light / wavelength

Wavelength = Velocity of light / frequency

= 3 x 10¹⁰ cm s^-1 / 3.02 x 10¹⁵ s^-1

= 0.993 x 10^-5 cm

1/ wavelength = 1/ 0.993 x 10^-5 cm

= 1.007 x 10⁵ cm^-1

= 100700 cm^-1cm-1

This indicates Rydberg's constant

Now the difference ( error ) =( 109678 - 100700 ) cm^-1

= 8978 cm^-1

% error = ( Error / Theoretical value ) x 100

= (8978/ 109678 ) x 100

= 8.18

=
