#1

For which of the following transition in H atom minimum wavelength is obtained..

  1. oo -->2
  2. oo --> 3
  3. 2--> 1
  4. 5--> 1
#2

Minimum wavelength means maximum energy. If oo represent infinity then answer will be D.

#3

#4

Calculate energy by the formula ,E=-13.6/z{1/n1^2-1/n2^2} ,and we also know that E=hc/lambda,where lambda is the wavelength, so energy is inversely proportional to wavelength. And hence you will get the answer
