Question

Satvik made light from a laser torch to fall on a prism. Will he be able to observe a band of

seven colours? Give reasons for your answer.​

Answer 1

Explanation:

This is called dispersion of light. However, a laser light is monochromatic in nature and produces just one spectrum of light. Therefore, Asha won't be able to see the spectrum of seven colours on passing a laser light through a prism.

Answer 2

No , laser light won't give the seven colors .

Explanation:

It is true that when we pass the white light via a prism , it splits into the seven colors , i.e. , VIBGYOR , which is the constituents of the white light .

But the laser light is monochromatic , with very high intensity in fixed direction , making it different from the ordinary white light , and hence would not split into seven colors .

Hence , the answer is - No , laser light won't give the seven colors .
