incorrect picture

The picture is incorrect. It's supposed to be a 30–60–90 triangle, but the angle labeled 90° is visibly an acute angle. Michael Hardy (talk) 02:44, 14 November 2011 (UTC)[reply]

I'll second that, is there a reference that might have a correct picture or confirm that the prism should not be a right angle one. Idyllic press (talk) 07:33, 3 May 2012 (UTC)[reply]

Why?

So a standard prism, like this, makes one wavelength of light appear at a particular angle. What is the importance of this devise? — Preceding unsigned comment added by Pehrlch (talk • contribs) 04:21, 30 May 2012 (UTC)[reply]

Is the deviation angle or prism angles dependent on the refractive index of the material for the selected frequency ?

Are they always made of the same type of (flint ?) glass ? - Rod57 (talk) 23:11, 8 April 2015 (UTC)[reply]
