Question

In the visible spectrum of sunlight through a prism the lower end of the

spectrum is

(a) Red (b) Green (c) Violet (d) Yellow​

Answer 1

Answer:

red is the answer to your question

Answer 2

1. White light is composed of seven colour bands (VIBGYOR), and when incident on the refracting face of the prism, each coloured ray deviates through a different angle depending on its wavelength.
2. The red rays deviate the least and have the longest wavelength, whereas the violet rays deviate the most and have the shortest wavelength.
3. Dispersion is caused by the differential deviation of rays.
4. As a result, in the spectrum of white light produced by a prism, the colour at the lower end of the spectrum is violet.

Hence, option C is correct.
