Reflection of Light

Explain reflection. What are different types of reflection? Explain.

The incident ray, normal and reflected ray all lie in the same _____.

If an incident ray makes an angle of $40$ degree with a plane mirror, then the angle of reflection will be _____ degree.

At the point of incidence, incident and reflected rays make _____ angle with the reflecting plane surface.

The incident ray, the normal at the point of incidence and the reflected ray all lie in the ________________.

The angle between the ____________ and the reflected ray is called the angle of reflection $\left(r\right).$

The angle between the normal and incident ray is called the _________________.

The light ray, which strikes any surface, is called the _____________.

Angle of incidence is _____________ equal to the angle of reflection.

According to the laws of reflection,
