Q4. In Spectrometer-Prism experiment, to find the refractive index of the prism. First find the least count of the vernier from the given figure 1. (25) Figure 1: Vernier of spectrometer Table 2: Reading for angle of prism Position V₁ V₂ MSR VSC Total MSR VSC Total 241⁰ 14/ 241⁰ 5/ Ti T2 301⁰ 10/ 121⁰ 10/ For angle of prism, positioned the telescope on left side (T1) and on right side (T₂). Table 3: Reading for deviation angle V₁ V2 MSR VSC Total MSR VSC Total 50⁰ 17/ 2310 25/ For minimum angle of deviation, the direct reading as follow. V₁ = 05/ and V₂ = 180 10/
