What is the value of refractive index on that Prism?
Answers
Explanation:
The refractive index of a prism can be calculated using the minimum deviation method governed by Schuster’s method. Using a spectrometer, find and record the deviation angle as well as the corresponding incident angle. Plot a graph between the two quantities. From the curve you plot, you'll get the angle of minimum deviation. Hence by the formula attached below, you can find the refractive index of the material of the any given prism.
The value of the refractive index of a glass prism lies somewhere between 1.4 to 1.6. The range is inclusive of various factors like uncertainty and errors in the measurement of:-
The angle of the prism
The angle of incidence
The angle of deviation.
Answer:
1.5
Explanation:
The refractive value of the material of a prism is 1.5 . When the prism is placed in minimum deviation position , angle of incidence is 51° . Calculate the angle of prism and angle of minimum deviation.
