1. In an experiment to find the index of refraction, n, of a block of glass, the angle of incidence, θi, and angle of refraction, θr, were measured a number of times as follows:(adsbygoogle = window.adsbygoogle || []).push({});

θi: 10° 20° 30° 40° 50°

θr: 7.0° 13.5° 20.0° 25.5° 31.0°

Given that the relationship between n, θi and θr is:

n =sin θi/sin θr

Calculate the best estimate for n with its uncertainty, and state the nal result with the

appropriate number of significant figures.

can someone explain to me how to form the equation?
