- 3 The Index Of Refraction For Glass Is 1 48 At T 20 0 C And Varies Linearly With Temperature With A Coefficient Of 1 (24.38 KiB) Viewed 53 times
3. The index of refraction for glass is 1.48 at T = 20.0° C and varies linearly with temperature, with a coefficient of 2.5 x 10-5/°C. The coefficient of linear expansion of the glass 5x10-6/°C. At T = 20.0° C the length of the rod is 3.00 cm. A Michelson interferometer has this glass rod in one arm, and the rod is being heated so that its temperature increases at a rate of 5.00°C/ min. The light source has wavelength λ = 589 nm, and and the rod initially is at T = 20.0° C. How many fringes cross the field of view each minute? 10 points
