Question

The colours of the spectrum can be recombined so as to give the effect of white light. How can you
demonstrate it?​

Answer 1

Answer:

white, cardboard ,compass ,protrectoe 7 colours in VIBGYOR sequency and pencil

Explanation:

take a piece of white cardboard and set the compass at 5 sentimeter radius to draw a circle on the cardboard cut out circle using the protector divide the cardboard circle into 7 equal VIBGYOR now 3 add a pencil through the centre of the circle with the wind at the bottom spine the disc

observation you will see that while the top in Spring at a high speed our eyes are unable to see the colours separately and the circle white this is white for all the seven which you have you should we come together resulting in white colour

Answer 2

The colors of the spectrum can be recombined so as to give the effect of white light. This can be demonstrated by a simple experiment as follows:

• Take 2 prisms and place them in such a way that one prism is inverted with respect to another.
• Now make a beam of light fall on the first erect prism.

• The prism will disperse light into seven colors due to the refraction.

• These seven colors are then received by the second inverted prism.

• The colors upon passing through the prism, get recombined into a white light and then emerges out from the prism.

• Thus, the seven colors disperse and then recombines into white light.
