Question

which are
the rules used to draw a ray diagrey
the laws of reflection of
light.​

Answer 1

Explanation:

The rules used for drawing ray diagrams for the formation of an image by a concave mirror are:

Rule 1: If the incident ray is parallel to the principal axis then the reflected ray passes through the focus of the concave mirror.

Rule 2: If the incident ray passes through the focus of the concave mirror, the reflected ray is parallel to the principle axis.

Rule 3: If the incident ray passes through the centre of curvature of the concave mirror, the reflected ray traces the same path.

Answer 2

LAWS OF REFLECTION OF LIGHT ARE

●the angle the incidence is equal to the angle of reflection

●the incidence ray the reflected ray and the normal to the mirror at the point of incidence all lie in the same plane

●the incident rat and the reflected ray lie on either side of the normal side
