Question

The middle colour in the sunlight spectrum is
A. Red
B. green
C. blue
D. orange

Answer 1

Hint: Visible light, also referred to as white light or the sunlight, consists of a collection of component colours. When it passes through the prism, the white light is separated into its component colours - red, orange, yellow, green, blue and violet. The separation of visible light into its different constituent colours is called dispersion.

Complete step by step answer:
The sunlight splits into seven colours namely violet, indigo, blue, green, yellow, orange, and red. The prism will split up the white light into seven different colours. This splitting of white light into its constituent colours is known as a dispersion of light. 

This makes it clear that the sunlight consists of several colours. Dispersion of light happens when white light is separated into its different constituent colours as a result of refraction and Snell's law. White light appears to be white since it consists of each and every colour on the visible spectrum. The order of colours is like this, violet, indigo, blue, green, yellow, orange and red. In this order and in the figure we can see that green is in the exact middle of all other colours.

So, the correct answer is “Option B”.

Note: The colour of the sun is found to be white. The sun emits all colours of the rainbow and we can call this combination "white". That is why so many different colours are visible in the natural world under the illumination of sunlight. As violet light is having a shorter wavelength, it is slowed more than red light having larger wavelengths. As a result violet light is bent the most while the red light is bent the least.
