Determination of the refractive index of the material of the prism
There are four different ways to find the refractive index of a material. Find the refractive index of glass prism. From the curve you plot, you'll get the angle of minimum deviation. Find the dispersive power of a. The refractive index of prism is given by the formula, ⇒ η = sin [ ( a + d) 2] / sin [ ( a + d) 2] sin a 2 sin a 2 where η is the refractive index of the prism, a is the angle of prism and d is the deviation. Turn the telescope parallel to collimator, and note the direct ray readings. · the given equilateral prism is placed on the prism table in such a way that refracting edge of the prism is facing the collimator. Make coincide the slit with the cross wire using fine angle adjusting slider. By using the snell’s law of refraction of light. The aim we try to calculate the refractive index (n) of the prism for various wavelengths of the mercury spectrum and then plot the dispersion and calibration curves using a prism spectrometer.
To determine dispersive power & refractive index of a prism using spectrometer and mercury source. A different value for every wavelength / color. Find the angle of minimum deviation. One can determine the refractive index by using the standard. Consider two colour green and violet, corresponding minimum deviation is d g and d v , corresponding refractive index is. Measure the position where a particular color. Let the angle of the prism is 50 degree and refractive index of the prism is 1.33. What is the formula to calculate refractive index of a medium? Find the minimum deviation for red, yellow, green and blue colour. Determination of refractive index using the spectrum of reflection from one surface at low angle of incidence close to normal (method 3.3). 2) determination of angle of the prism (a) · the slit is illuminated by yellow light from sodium vapour lamp.
