Explain
1. Convergent beam of light.
2. Divergent beam of light.
3. Parallel beam of light.
with diagram and definition.
Answers
Answer is
1. When light rays from different points constantly keep coming closer together and finally meet at a point, then the light beam is known as a convergent beam of light.
2. Rays of light coming from a point travel in various directions they form a divergent beam. For Example - Rays coming out from a glowing bulb or a candle or a car headlight form a divergent beam.
3. A large number of rays travel parallel to each other, then we call such collection of rays as parallel beam of light Rays. ... when rays of light starting from a point travel in various directions, then such rays are termed as Divergent beam of rays.
Please mark me as Brainiliest answer.
Answer:
A convergent beam of light: Light rays comes together (converges) after reflection and refraction at a single point known as the focus. Divergent beam of light : Light rays from a point source of light travel in all directions, moving away with time. Such a beam of light is called a divergent beam of light.
