While determining the refractive index of a liquid experimentally, the microscope was focussed at the bottom of a beaker, when its reading was 3.965 cm. on pouring liquid upto a height 2.537 cm inside the beaker, the reading of the refocussed microscope was 3.348 cm. Find the refractive index of the liquid.

A luminous object O is located at the bottom of a big pool of liquid of refractive index `mu` and depth h. The object O emits rays upwards in all dire
Correct Answer - Rays beyond the circle are totally reflected into the liquid, Radius `=(h)/(sqrt(mu^(2)-1))` Area `=(pi h^(2))/(mu^(2)-1)`

The pressure reading in a thermometer at steam point is 1.367 × 10^3 Pa. What is pressure reading at triple point knowing the linear relationship
Given: P = 1.367 × 103 Pa at steam point (T) i.e., at 273.15 + 100 = 373.15 K. Linear relationship between temperature and pressure means that. P ∝ T ⇒ P1T1 = P2T2 To find:...
