Question

what is the glancing angle in case of normal incidence​

Answer 1

Explanation:

90 degrees

Hint –

The glancing angle of incidence is defined as the angle between the ray of the incident on the plane surface and the surface. It is the component of the angle of incidence. Also, the angle of incidence + glancing angle of incidence is equal to 90 degrees.

Answer 2

Answer:

90 degrees

Explanation:

The glancing angle of incidence is defined as the angle between the ray of the incident on the plane surface and the surface. It is the component of the angle of incidence. Also, the angle of incidence + glancing angle of incidence is equal to 90 degrees.
