Joint Entrance Examination/2000 Screening/Q033 Glass slab in water and total internal reflection


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

Here's the question...

A rectangular glass slab ABCD of refractive index n 1 is immersed in water of refractive index n2 (n1 > n2). A ray of light is incident at the surface AB of the slab as shown. The maximum value of the angle of incidence α?max, such that the ray comes out only from the other surface CD, is given by...
