The critical angle is the angle of incidence above which total internal reflection occurs. The angle of incidence is measured with respect to the normal at the refractive boundary (see diagram illustrating Snell's law). Consider a light ray passing from glass into air.

[@Nada-qn2rg]

Since you commented only 2 months ago, can I ask you a question? If the critical angle is the incidence angle, how come the i can become equal to the c angle, aren't they the same?

[@MagnusFAN]

Thank you so much sir.

sir did angle of incidence greater than critical angle means Graeter than 90 degree

[@roshanara7191]

Nopes , actually it means that incidence angle is greater than critical angle (incidence angle with refracted angle equal to 90 degree) . I hope it will help you
