Two parallel rays of Red and Violet travelling through the air, meet the air-glass boundary as shown in the above figure. Will their paths inside the glass be parallel? Give a reason for your answer.

उत्तर
No.
Reason: Deviation suffered by each ray will be different because the refractive index is different for different colours of light.
