What is means by a parallel beam
Answers
Answer:
PARALLEL BEAM - WHEN THE RAYS OF LIGHT TRAVEL PARALLEL TO EACH OTHER , THEN THE COLLECTION OF SUCH RAYS IS CALLED PARALLEL BEAM . 2)DIVERGENT BEAM - WHEN THE RAYS OF LIGHT START FROM A POINT AND TRAVEL IN VARIOUS DIRECTION ,THEN THE COLLECTION OF SUCH RAYS ARE CALLED DIVERGENT BEAM
Answer:
Parallel beam of light :
when a large number of rays travel parallel to each other, then we call such collection of rays as parallel beam of light Rays.
Examples:
1. The rays of sun entering a room through an open window
2. The rays of light coming out of search light or spot light constitutes parallel beam of light rays.
Divergent Beam of rays:
when rays of light starting from a point travel in various directions, then such rays are termed as Divergent beam of rays.
Example:
1. Rays coming out from burning candle.
2. Rays coming out from the car head light .
3. Rays coming out from light bulb.
Convergent Beam of light Rays:
when the rays of light coming from different directions meet a point, then such rays constitutes convergent rays.
Examples:
1. Parallel beam of sunlight are made to incident on solar cooker consisting of concave mirror so that the rays converge at focus point.
2. The rays received by camera are converging lens
3. The rays enetering in our eyes converge on the retina.
