to determine the refractive index of a substance
or to Verify Snells Law
Title Verification of Snell’s law of refraction.
Apparatus
Glass / persex block, pins, a light box (laser) styrofoam.
Method

Alternative Method To determine the refractive index of a transparent material
Draw the outline of the block on the page.
Line up 2 pins as so they make a line to the block, which makes an angle to the block.
Look through the block
place a pin so it blocks out the image of the 2 pins through the glass block
place another pin in so it blocks the line of the 3 pins when looking through the glass block
Draw lines that join the dot to the glass block
then under the block join the two points, where the drawn lines meet the outline of the block, to each other.
refractive index = Sin i/Sin r = n
