Answer 1

1)ray of light is a narrw beam of light which moves in a particular direction.
2)it is a directional projection of enrgy radiatin frm the light source.
3)It is a beam of light which r parallel 2 each other.
4)the light rays which meet at a cerain point.
5)rays which r reflctd back.

RAY OF LIGHT

A very narrow path of light described by a straight line drawn in the direction of propagation of light is called a ray of light .

BEAM OF LIGHT

A broader bundle of light rays is called a beam of light .

PARALLEL BEAM

A beam of light consisting of parallel rays of light is called parallel beam of light .

DIVERGENT BEAM

A beam of light consisting of rays diverging from a point source is called divergent beam of light .

CONVERGENT BEAM

A beam of light consisting of rays coming closer to each other , ultimately to meet at a point , is called convergent beam of light .
