The lens governing the behavior of the rays namely rectilinear propagation laws of reflection and refraction can be summarised in one fundamental law known as Fermat's principle. According to this principle a ray of light travels from one point to another such that the time taken is at a stationary value (maximum or minimum). if c is the velocity of light in a vacuum the velocity in a medium of refractive index mu is (c)/(mu) hence time taken to travel a distance l is (mul)/(c) if the light passes through a number of media, the total time taken is ((1)/(c))summul or (1)/(c)intmudl if refractive index varies continuously. Now summul is the total path, so that fermat's principle states that the path of a ray is such that the optical path in at a stationary value. this principle is obviously in agreement with the fact that the ray are straight lines i a homogenous isotropic medium. it is found that it also agrees with the classical laws of reflection and refraction. Q. If refractive index of a slab varies as mu=1+x^(2) where x is measured from one end then optical path length of a slab of thickness 1 m is

Two solid bodies of equal mass m initially at T = 0^(@)C are heated at a uniform and same rate under identical conditions. The temperature of the first object with latent heat L_(1) and specific heat capacity in solid state C_(1) changes according to graph 1 on the diagram. the temperature of the second object withe latent heat L_(2) and specific heat capacity in solid state C_(2) changes according to graph 2 on the diagram. based on what is shown on the graph, the latent heat L_(1) and L_(2) and the specific heat capacities C_(1) and C_(2) in solid state obey which of the following relationships?

For a substance A, vapour pressure of liquid and solid state at temperature 400K is 0.1 "bar" and 0.16 "bar" respectively. What will be Gibbs free energy change for the following process. A(s)[0.1"bar",400K,n=1]toA(l) [0.16"bar",400K,n=1]

In the reaction, 3BrO^(-)rarrBrO_(3)^(-)+2Br^(-) (aqueous alkaline medium at 80^(@)C ) the vlaue of the rate constant in the rate law in terms of --(d)/(dt)[BrO^(-)] is 0.056 L "mol"^(-1)s^(-1) . What will be the rate constant when the law is stated in terms of (d)/(dt)[BrO^(-)] ?

Collidal solution is a heterogeneous solution which contains particle of intermediate size, i.e., (diameter between 1 and 1000 nm) colloidal is not a substance but it is a state of a substance which depends upon the molecular size. Colloidal solutions are intermediate between ture solution and suspensions. The colloidal solution of a solid as the disperesed ohases and a gas as the dispersed medium is called
