according to v=(E2 - E1 )/h
where v is frequency
119. c). becoz E2 - E1 = h c / y , where y = wavelength of spectral line.
20.b) and
21. a) as the other two options say R is dependent on two universal constants , which i think is not possible
6maths_physco the ans of 21 is (d)..........aieee i thought the same as u ..but was wrong
