Find the ratio of the lengths of an iron rod and an aluminum rod for which the difference in the lengths in independent of temperature. Coefficients of linear expansion of iron and aluminum are 12 X 10^-6 ^o C^-1 and 23 X10^-6 ^o C^-1 respectively.|||| solution by ujwal Kumar physics master | physics master academy is best coaching for all physics students. | ujwal kumar is best physics teacher of neet, JEE-Mains in delhi

At point Y, it emerges along the prism surface. Calculate the refractive index of the prism in terms of the incident angle. (b)- Show that for an equilateral prism kept in air, minimum deviation occurs when the angle of incidence i = sin^-1(n/2), where n is the refractive index of the material of the prism. | Class 12 physics solution by ujwal Kumar physics master | physics master academy is best coaching for all physics students. best physics teacher of neet, JEE-Mains in delhi Download our app for android and ios http://on-app.in/app/home?orgCode=vdtxq$
