we have a soft wood board and pins .. the classic good ol' lab ways. thanks how do i close this thread?

okay guys ... i figured it out i think there will be no error .. thank you sophiecentaur it is because the angle of incidence will be the same as angle of refraction on face 1 as well as face 2 . there will be lateral deviation but we don't actually need that ... our aim is the angle of...

it would differ for different angle of incidences ... because it is a sine proportion ...

@mfb i know where i went wrong ... actually you can't find the error of the hollow prism .. it is just like you have a very small glass prism in a water/liquid prism .. the error in the measurement of r will be different for each case

i think i got my answer my theory was just wrong ... the

i have recently made a hollow prism for my science exhibition in my school ... to find refractive indices of fluids. i made it using 3 rectangular pieces of glass (0.5cm) on a glass triangular base ..with obviously a hollow part in the middle it worked perfectly fine with water i got n=1.33...
