Joint Entrance Examination/AIEEE 2009/Q075 TRANSITION

Welcome to the Highschool Help Forum!

The forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content.

The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there.

If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum

Lastly, thanks for joining in the site's development process! It matters!

Here's the question...

Q75. The transition from the state n = 4 to n = 3 in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from

  • (1) 3 → 2
  • (2) 4 → 2
  • (3) 5 → 4
  • (4) 2 → 1

Additional notes

SOLUTION:[3] Energy gap between 4th and 3rd state is more than the gap between 5th and 4th state, And ΔE = hc/λ λ5 – 4 > λ4 – 3
