To determine the refractive index of a prism by using a spectrometer.
How To Find Refractive Index Of Prism Using Spectrometer - How To Find. The transmitted light ray has small deviation of the path from the. Place the edge of prism, pointed towards collimator.
To determine the refractive index of a prism by using a spectrometer.
The refractive index of a prism can be calculated using the minimum deviation method governed by schuster’s method. Hence by the formula attached below, you can find. According to figure 3 at low angle of. Plot a graph between the two quantities. By using the snell’s law of refraction of light. Find the refractive index of glass prism. Consider two colour green and violet, corresponding minimum deviation is d g and d v , corresponding refractive index is. There are four different ways to find the refractive index of a material. This angle is called angle of minimum deviation ( m). The scheme for determination of the refractive index according to this method corresponds to the area 2 in figure 3.
Hence, find the angle of prism. Move the telescope in the opposite direction and do the same. Using a spectrometer, find and record the deviation angle as well as the corresponding incident angle. Place the edge of prism, pointed towards collimator. Then note the reading in the tabular coloumn. Apparatus required a) mercury lamp (as source of white light) b) spectrometer c) prism 3. To determine the refractive index of the material of a prism. 5.carefully remove the prism from the prism table. Plot a graph between the two quantities. Determination of refractive index using the spectrum of reflection from one surface at low angle of incidence close to normal (method 3.3). Move the telescope using telescope slider up to see the slit on side.
