Rainbow is an example for continuous spectrum - explain
Answers
Explanation:
A rainbow is a natural spectrum appearing in the sky just after a rain shower.
It is caused by dispersion of sunlight by tiny water droplets present in atmosphere.
In rainbow there are no sharp boundaries in between colours.
Such a spectrum in which there are no sharp boundaries in between colours is known as continuous spectrum.
So, rainbow is also a continuous spectrum.
●When light is dispersed, a bright spectrum of continuously distributed colours is obtained on a dark back ground.
● The colours gradually change, there are no sharp boundaries.
●Such a spectrum is known as continuous spectrum of emission.
●This type of continuous spectrum of emission can be observed in Rainbow which is a natural spectrum appearing in the sky just after a rain shown due to dispersion of sunlight by tiny water droplets present in atmosphere which act like small prism.
