Solution
The correct option is C Sir Issac Newton
Correct answer
is (a) Sir Issac Newton.
In 1666,
during one of his optical experiments, Newton passed a beam of
sunlight through a glass prism. The glass prism split the light into a band of
seven colours on his wall. This phenomena is known as dispersion of light
He called this
band of colours the ‘spectrum’. Thus the spectrum is a band of seven colours
which is obtained by splitting of white light by a glass prism.
