Answer:
The Refractive Index of glass is maximum for:
A) blue
Information About Refractive Index:-
☞ a ray of light that travels obliquely from one transparent medium into another will change its direction in the second medium.
☞ The extent of the change in direction that takes place in a given pair of media is expressed in terms of the refractive index, the “constant” appearing on the right-hand side of Eq.
☞ The refractive index can be linked to an important physical quantity, the relative speed of propagation of light in different media.
☞ It turns out that light propagates with different speeds in different media. Light travels the fastest in vacuum with the highest speed of 3×108 m s–1.
☞ In air, the speed of light is only marginally less, compared to that in vacuum. It reduces considerably in glass or water.
☞ The value of the refractive index for a given pair of media depends upon the speed of light in the two media, as given below.
