There are different ways to investigate refraction in rectangular blocks. In this required practical activity, it is important to: make, measure and record the angles of incidence accurately using a ...

Plot a graph of angle of incidence, i in o on the y-axis against angle of refraction, r in o on the x-axis and draw the line of best fit. We can see from the graph that as the angle of incidence, i, ...

If the light rays are travelling from one medium to another they change their direction at the boundary between two mediums. When the light rays either bend or change their direction while passing ...
