Determination of the refractive index of the material of the prism
How To Find Refractive Index Of Prism Using Spectrometer - How To Find. To determine dispersive power & refractive index of a prism using spectrometer and mercury source. · the given equilateral prism is placed on the prism table in such a way that refracting edge of the prism is facing the collimator.
Determination of the refractive index of the material of the prism
Apparatus required a) mercury lamp (as source of white light) b) spectrometer c) prism 3. Find the difference between two angle ie 2θ. Refractive index of the material of the prism is determined by using eq.(12) 5 When a beam of light strikes on the surface of transparent material(glass, water, quartz crystal, etc.), the portion of the light is transmitted and other portion is reflected. · the given equilateral prism is placed on the prism table in such a way that refracting edge of the prism is facing the collimator. The transmitted light ray has small deviation of the path from the. 2) determination of angle of the prism (a) · the slit is illuminated by yellow light from sodium vapour lamp. Find the angle of minimum deviation. A narrow beam of white light incident on the prism. 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.
Move the telescope using telescope slider up to see the slit on side. In this video, i have elaboratory discussed how to perform the practical to find refractive index of prism using spectrometer and how to find refractive. Move the telescope using telescope slider up to see the slit on side. With the help of refractive index calculator; Then note the reading in the tabular column. A narrow beam of white light incident on the prism. Apparatus required a) mercury lamp (as source of white light) b) spectrometer c) prism 3. Move the telescope using telescope slider up to see the slit on side. Find the difference between two angle ie 2θ. Spectrometer, prism, prism clamp, sodium vapour lamp, lens. The scheme for determination of the refractive index according to this method corresponds to the area 2 in figure 3.
