Which of the following statement is correct?
Options
- AIn primary rainbow, observer sees red colour on the top and violet on the bottom
- BIn primary rainbow, observer sees violet colour on the top and red on the bottom
- CIn primary rainbow, light wave suffers total internal reflection twice before coming out of water drops
- DPrimary rainbow is less bright than secondary rainbow.
Correct answer
A. In primary rainbow, observer sees red colour on the top and violet on the bottom
Step-by-step solution
In primary rainbow, red colour is at top and violet is at bottom. The colours are in the order of violet, indigo, blue, green, yellow, orange and red (VIBGYOR). Since violet colour has the smallest wavelength, in the primary rainbow, it suffers maximum refraction. That is why it appears on the innermost position.
Intensity of secondary rainbow is less in comparison to primary rainbow.
