Refraction Of Light Lab
The results we obtained show that on average, we calculated a sin i over sin R to be 1.34 units. Also we can say that as the angle of incidence increased, the angle of refraction tended to increase proportionally. As the sin of i increased, the sin of R also increased. Below you can see the exact relationship between the sin of the incidence angle (i) versus the sin of the refracted angle (R). To find the slope of the…...

I believe that femininity and masculinity is due to biological differences to a certain extent, as there is a difference between female anatomy, hormones and genes and that of a male. Schiebinger (1987, p. 9-70) claimed that…...
