Dispersion

Question

we know that when light of different colours falll on an object, it absorbs some colours and reflect others, which becomes the colour of the object. so, if light has only 7 colours, that are: violet, indigo, blue, green,yellow,orange and red, how can we see other colours under white light?

Solution

When there is a dispersion of Light there is a spectra of 7 colours ,but due to overlapping of these colours there are so many colours which we can see.

Q. Instead of all 7 colours (violet, indigo, blue, green, yellow, orange, red) if the sun only emits green, yellow, orange and red, what would be the possible colour of the sky?

Q. We know that when see something of some specific colour , it is the the colour of light that is being reflected by it .Let say a rose . Rose will reflect only red light and will absorbed all other light. So on this basis , can we say that the energy of rose is increasing since it is absorbing some amount of light(light is also a form of energy)?

Q. Seven men- P,Q,R,S,T,U and V are standing in a queue in that order. Each one is wearing a cap of different colour-violet, indigo, blue, green, yellow, orage and red. S is able to see in front of him green and blue, but not violet. T can see violet and yellow, but not red. V can see caps of all the colours other than orange. If T is wearing an indigo coloured cap, find colour of the cap worn by U.

Q. A light bulb

14 W

emits white light, which is a mixture of various colours in the spectrum. The energy is distributed among the seven colours i.e., red, orange, yellow, green, purple, indigo and blue. If the number of photons

n

emitted from each colour is equal, then the frequency of green colour is (The frequency of all the colours of white light are in AP)

(\frac{n}{time}) = 5.5 \times 10^{18} s^{- 1}

If the white colour light is falling on a blue coloured object then what colour is reflected back?
