The wavelength of a spectral line emitted by hydrogen atom in the Lyma...
Given:
Wavelength of spectral line in Lyman series = 16/15Rcm
To find:
Value of n2
Formula:
1/λ = R(1 - 1/n2^2)
Solution:
- Convert given wavelength to meters:
1/λ = 16/15R = 16/15 * 1.097 * 10^7 m^-1 = 1.169 * 10^7 m^-1
- Substitute values in formula:
1/1.169 * 10^7 = 1.097 * 10^7 (1 - 1/n2^2)
- Solve for n2:
n2 = 4
Therefore, the value of n2 is 4. Hence, the correct answer is option 'C'.
