Definition: The angle of incidence is defined as the angle made by the incident ray with the normal to the point of incidence.
This is an example of an ill-framed question which creates confusion in the mind of the students.
So in case if the question means that “the incident ray of light makes an angle of 50 degrees with the glass slab” then we get the following situation and the angle of incidence will be 90∘−50∘=40∘ 90∘−50∘=40∘:
