# 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!
| Original Question by 164.100.170.4 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 Posted by 164.100.170.4 05:30, 24 September 2009 (UTC) Post a reply! | What's Up?

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
λ$_{5–4}$ > λ$_{4–3}$
