Question

If one measures the index of refraction to be 1.1, this material would be

More dense than vacuum

More dense than acrylic

More dense than water

Less dense than air

Answer 1

using Snell's law

sin i / sin r = u

sin r = sin i / u

as u > 1, so value of (sin i / u) must be smaller than sin i

and hence angle corresponding to refraction "r" will be less than 'i' it mens that light bend towards the normal

so, the material medium is more dense than the medium from which the incident light projected and vice versa.

so

option (a) is true

option ( b) false

option (c). false

option (d) false
