The half transition that needed for radiation with longer wavelength than n = 1 to the n = 3 level is to be determined from the given option. Concept introduction: Electronic transitions that take place in excited H atom is, 1. Lyman series: electronic transitions take place to the n = 1 level and it is in ultraviolet region. 2. Balmer series: electronic transitions take place from n > 2 to the n = 2 level and it is in visible region. 3. Ritz-Paschen series: electronic transitions take place from n > 3 to the n = 3 level and it is in infrared region. 4. Brackett series: electronic transitions take place from n > 4 to the n = 4 level. 5. Pfund series: electronic transitions take place from n > 5 to the n = 5 level As the energy gap between two transition states increases the frequency of the radiation emitted also increases E = h ν

Chapter 6, Problem 20PS
Interpretation Introduction

Interpretation:

The half transition that needed for radiation with longer wavelength than n=1 to the n=3 level is to be determined from the given option.

Concept introduction:

  • Electronic transitions that take place in excited H atom is,
    1. 1. Lyman series: electronic transitions take place to the n=1 level and it is in ultraviolet region.
  1. 2. Balmer series: electronic transitions take place from n>2 to the n=2 level and it is in visible region.
  2. 3. Ritz-Paschen series: electronic transitions take place from n>3 to the n=3 level and it is in infrared region.
  3. 4. Brackett series: electronic transitions take place from n>4 to the n=4 level.
  4. 5. Pfund series: electronic transitions take place from n>5 to the n=5 level

As the energy gap between two transition states increases the frequency of the radiation emitted also increasesE=hν
