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 Dharav talk

Some text goes here

Electrons with energy 80keV are incident on the tungsten target of an X-Ray tube. K-shell electrons of tungsten have -72.5 keV energy. X-rays emitted by the tube contain only

  • (A) a continuous X-ray spectrum (Bremsstrahlung) with a minimum wavelength of - 0.155 A.
  • (B) a continuous X-ray spectrum (Bremsstrahlung) with all wavelengths.
  • (C) the characteristic X-ray spectrum of tungsten.
  • (D) a continuous X-ray spectrum (Bremsstrahlung) with a minimum wavelength of -0.155 , and the characteristic X-ray spectrum of tungsten.
