Question

When light travels from one medium to another medium, it is refracted and enters the new
medium at a different angle. The degree of bending of the light's path depends on the angle
that the incident beam of light makes with the surface of the prism, and on the ratio between
the refractive indices of the two media. Refractive index, also called index of refraction,
measure of the bending of a ray of light when passing from one medium into another. Some
measurements are taken for the refractive index of glass prism in the laboratory. In
successive measurements the reading turns out to be 1.54, 1.53, 1.44, 1.54, 1.56 and 1.45.
1. The mean refractive index of glass prism
a) 1.5 b) 1.51 c) 9.0 d) 9.02
2. The mean absolute error in the measurement of refractive index
a) 0.02 b) 0.03 c) 0.04 d) 0.05

3. The relative error in the measurement of refractive index
a) 0.02 b) 0.03 c) 0.04 d) 0.05
4. The Refractive index of glass with percentage error
a) 1.5 ± 2% b) 9.0 ± 2% c) 1.51 ± 3% d) 9.02 ± 3%

Answer 1

Answer:

When light travels from one medium to another medium, it is refracted and enters the new medium at a different angle. The degree of bending of the light's path depends on the angle that the incident beam of light makes with the surface of the prism, and on the ratio between the refractive indices of the two media.
