What is the critical angle for light going from crown glass to air?

The critical angle for a diamond in air is 24 degrees, while the critical angle for glass is 41 degrees.

Explanation:

Rays exiting the material at an angle less than the critical angle will be refracted, and rays incident on the interface at greater than the critical angle will be totally reflected back inside the material.
