Expert Answer

Wavelength can be calculated by-

1 over lambda equals R Z squared left parenthesis 1 over n subscript 1 squared minus 1 over n subscript 2 squared right parenthesis I f space n subscript 1 equals 3 space a n d space n subscript 2 equals infinity t h a n space 1 over lambda equals 10 to the power of negative 7 end exponent cross times 1 squared cross times open parentheses 1 squared over 3 squared minus 1 squared over infinity squared close parentheses equals 10 to the power of negative 7 end exponent over 9 m to the power of negative 1 end exponent lambda equals 900 n m

Correct answer is not mentioned in options, you can check by putting values of n₁ and n₂ in equation.
