Web5. Refer to Fig. 0.4 to learn how to read the Refractive Index Scale. The index is read 1 where the vertical cross hair intersects the top (n d) scale. 6. Hold the power switch in the down position. Use the hand wheel on the right side of the case to set the index scale (visible through the eyepiece) to read 1.3333, the refractive index of water.
WebApr 1, 2024 · Hint:For the maximum value of refractive index, the angle of incident is with respect to the surface of the prism and since there is only refraction of light takes place so there will not be total internal reflection and use Snell’s law and thermodynamic property. Formula used: According to the Snell’s law, the refractive index is given by $\mu = … Web7. Two points masses, m each carrying charges − q and + q are attached to the ends of a mass less rigid non-conducting wire of length ′ L ′.When this arrangement is placed in a uniform electric field, then it deflects through an angle i.The minimum time needed by rod to align itself along the field is
WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v. It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam. WebMathematically, ∠A and ∠Q form 180o and the angle of prism of (A) is r 1 +r 2. r 1 = angle of refraction inside the prism. r 2 = angle of refraction outside the prism. i1= angle of incidence when the light is entering the prism. i2 = angle of emergence while exiting prism. For an angle of minimum deviation, i 1 = i 2 =i. δ min = 2i-A
