Question

Identify three rays that can be used for constructing ray diagrams:
Explain why these rays are especially chosen for making ray diagrams.
For each of the rays identified,state the path they are expected to follow.

Answer 1

Answer:

Convenient rays fir the cinstruction of ray diagrams:

• a ray passing through the centre of curvature is reflected along its own path :-a line joining the centre of curvature to any point on the surface of mirror is always normal to it does a Ray passing through the centre of curvature is incident normally on the spherical mirror and is take another conveniently for ray diagram
• ray parallel to the principal axis :-A Ray of light incident parallel to the principal Axis after reflection passes through the focus in case of a concave mirror appears to come from the focus in case of a convex mirror
• a ray passing through the focus :-are passing through the focus in case of a concave mirror for appearing to pass through the focus in case of a convex mirror gets reflected parallel to the principal axis

for constructing a ray diagram at least two days of convenience whose parts can be traced after reflection is taken and the Three rays parts are known to us that's why this 3 rays especially taken for the construction of a ray diagram ...

Hope it helps!!✌
