A) reflection and diffraction
B) refraction and scattering
C) dispersion and total internal reflection
D) interference only
Correct Answer: C
Solution :
| When white light from sun falls on rain drops, sometimes a band of different colours in form of a circular arc is seen in the sky opposite the sun. This is called the rainbow. |
| The reason of origin of rainbow is that the small drops of water behave like a prism for the white sun light due to which refraction, dispersion and total internal reflection of white light occurs from the water drops. |
