1. Question 1

   Q1. The wavelength of the first line of Lyman series is given by

   • A) 1/λ = R(1/1^2 - 1/2^2)
   • B) 1/λ = R(1/2^2 - 1/3^2)
   • C) 1/λ = R(1/1^2 - 1/3^2)
   • D) 1/λ = R(1/3^2 - 1/4^2)

   Answer: 1/λ = R(1/1^2 - 1/2^2)

   Explanation: First line of Lyman series corresponds to transition from n=2 to n=1; option B is incorrect because it's for Balmer series.
