Refraction of light is the phenomenon which takes place due to the difference in the ___________ of the mediums.

Yellow light is refracted through a prism producing minimum deviation. If i 1 and i 2 denote the angle of incidence and emergence for this prism, then (i) i 1 = i 2 (ii) i 1 > i 2 (iii) i 1 < i 2 (iv) i 1 + i 2 = 90 o
