- Page 2 The telescope mounted on heavy bearings can be rotated about the vertical central axis of the scale. A vernier reading to 0.1 is fixed to telescope arm. There is one clamping screw to fix the telescope and a tangent screw for slow motion of the telescope. © EISCO SCIENTIFIC www.eiscolabs.com...
- Page 3 AC and along AT from the face AB each time the slit falling upon the across wires. The Difference between the two readings (angle T AT ) is equal to twice the angle of prism i.e, 2A where A is angle of the prism. Half this difference gives the angles A. © EISCO SCIENTIFIC www.eiscolabs.com...

- Page 5 The angle subtended by the two faces here is the angle of the prism. This angle and the angle of minimum deviation are determined and here the refractive index is found as in the above experiment. © EISCO SCIENTIFIC www.eiscolabs.com...
- Page 6 The calibration curve will be as shown. If the slope of the graph for any particular wave length is found the resolving power of the prism can be calculated Where t = length of the base of the prism and is tangent of the angle of the slope. © EISCO SCIENTIFIC www.eiscolabs.com...
