Question

2. Rahul made light from a laser torch to fall on a prism. Will he be able to observe a band of seven colors? Explain with a reason.

Answer 1

Answer:

No

Explanation:

When white light falls on a prism, it gets separated into seven different wavelengths starting from violet to red.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

Answer + Explanation:

Rahul will be able to see seven bands of colour only if the light is WHITE because ONLY WHITE LIGHT HAS THOSE SEVEN COLOURS i.e. VIBGYOR.
