Mitosis produces 2 haploid cells that are identical to each other while meiosis produces 4 haploid cells that are genetically uniqu
Answer: Wavelength associated with the fifth line is 397 nm
Explanation:

= Wavelength of radiation
E= energy
For fifth line in the H atom spectrum in the balmer series will be from n= 2 to n=7.
Using Rydberg's Equation:

Where,
= Wavelength of radiation
= Rydberg's Constant =
= Higher energy level = 7
= Lower energy level = 2 (Balmer series)
Putting the values, in above equation, we get



Thus wavelength λ associated with the fifth line is 397 nm
