Question

explain the rules for making a ray diagram? explain by draw diagrams.

Answer 1

there are only three rules for making ray diagram 1. abeam of ray passing through focus will be parallel to principal axis after reflections.
2. abeam of ray incident through center of curvature Will reflect in same directions.
3. a beam of ray incident parallel to principal axis must pass through focus of spherical mirror or lenses

Answer 2

$\sf{there \: are \: 4 \: rules \: for \: making \: ray \: diagram}$

• $\sf{a \: ray \: parallel \: to \: principal \: axis} \\ \sf{\: will \: pass \: through \: focus \: } \\ \sf{after \: reflection.}$
• $\sf{a \: ray \: comes \: from \: focus \: after} \\ \sf{ \: reflection \: will \: parallel \: to \: } \\ \sf{principal \: axis.}$
• $\sf{a \: ray \:directed \: towards \: centre \: of} \\ \sf { \: curvature \: will \: recast \: its \: way.} \:$
• $\sf{a \: ray \: of \: light \: falling \: on \: the \: pole }\\ \sf{ get \: reflected \: at \: same \: angle \: on \: the \: }\\ \sf{ other \: side \: of \: principal \: axis.}$
