How is the angle of reflection determined in Bragg's spectrometer method ? 

Explain the Angle of reflection

How is the temperature of stars determined by

How the order of a reaction can be determined by integral equation method ?

If a ray of light in a denser medium strikes a rarer medium at an angle of incidence i, the angles of reflection and refraction are respectively, r and r' If the reflected and refraction rays are at right angles to each other, the critical angle for the given pair of media is

In the given figure,the angle of reflection is

A ray of light is incident at an angle i from denser to rare medium. The reflected and the refracted rays are mutually perpendicular. The angle of reflection and the angle of refraction are respectively r and r'. Then the critical angle will be:
