Answer:
<h2>index of refraction = 1.69</h2><h2>percentage error = 10.58%</h2>Explanation:
According to Snell's law, the ratio of the sine of angle of incidence to the sine of angle of refraction is a constant for a given pair of media. The constant is known as the refractive index.
Mathematically
i = angle of incidence measured = 63.5°
r = angle of refraction measured = 32°
n = refractive index
The index fraction calculated is approx. 1.69.
If the index of refraction of a clear plastic as listed in the book is 1.89 and the calculated is 1.69, the percentage error will be calculated as thus;
%error =
%error =
%error =
%error = 10.58%
