"Angle made by incident ray with reflecting surface is incidence angle” convinced ?

What is incidence angle ?

Light of wavelength 5000 Å incidents on reflecting surface, then for ...... value of incidence angle, reflected and incident ray will be perpendicular.

Refracted ray from an equilateral prism will be parallel to surface is incidence angle is ....... ( mu =1.5)

When a ray of light enters into the medium of refractive index of mu , angle of refraction is half of angle of incidence so angle of incidence = ......

If one face of a prism angle 30^(@) "and" mu= sqrt2 is silvered , the incident ray retraces its initial path. What is the angle of incidence?

A ray of light travelling in water is incident on its surface open to air. The angle of incidence is theta , which is less than the critical angle. Then there will be

The angle of incidence for a ray of light at a refracting surface of a prism is 45^@ . The angle of prism is 60^@ . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are

Radiation of energy E is incident on complete reflecting surface.Momentum imparted to surface will be……
