Refractive Index

Showing 1 to 3 of 3

I got a bit stuck on this: 

what is the experiment to determine the refractive index of glass, using a glass box?

Bending light? refraction?

refractive index    n= 1/sinc

c is the critical angle. this is the angle the light is passed into the block from the normal and the light travels at 90 degrees when it is refracted again
