A) red
B) green
C) yellow
D) violet
Correct Answer: A
Solution :
Refractive index \[(\mu )=\frac{real\,depth}{apparent\,depth}\] \[\Rightarrow \] \[\mu \,\,\alpha \,\,\frac{1}{apparent\,\,depth}\] Since, violet light is refracted the maximum and red light are least, the refractive index is maximum for violet colour and minimum for red colour. Hence, letter which appears minimum raised are red.You need to login to perform this action.
