how refraction of light takes place through prism?
1 Answer
Apoorva Arora
Light changes speed as it moves from one medium to another (for example, from air into the glass of the prism). This speed-change causes light striking the boundary between two media at an angle to be refracted and enter the new medium at a different angle (Huyghens principle), or to be reflected away from it. The amount of reflected light and the degree of bending of the light's path will depend on the angle that the incident beam of light makes with the surface, and on the ratio between the refractive indices of the two media (Snell's law).

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
