" Derine "(mu_(2))/(v)-(k_(1))/(u)=(42-k_(1))/(R)

Prove that (-mu_1)/(u)+(mu_2)/(v) = (mu_2 - mu_1)/( R) when refraction occurs from rarer to denser medium at a concave spherical refracting surface.

Derive the relation:- frac(mu_2)(v) - frac(mu_1)(u) = frac(mu_2 - mu_1) (R) when light undergoes refraction fromoptically rarer to optically denser medium at curved surface.

For the consecutive unimolecular-type first-order reaction A overset(k_(1))rarr R overset(k_(2))rarr S , the concentration of component R, C_( R) at any time t is given by - C_(R ) = C_(OA)K_(1)[e^(-k_(1)t)/((k_(2)-k_(1))) +e^(-k_(2)t)/((k_(1)-k_(2)))] if C_(A) = C_(AO), C_(R ) = C_(RO) = 0 at t = 0 The time at which the maximum concentration of R occurs is -

Let u-=ax+by+a root(3)(b)=0,v-=bx-ay+b root(3)(a)=0,a,b in R be two straight lines.The equations of the bisectors of the angle formed by k_(1)u-k_(2)v=0 and k_(1)u+k_(2)v=0, for nonzero and real k_(1) and k_(2) are u=0 (b) k_(2)u+k_(1)v=0k_(2)u-k_(1)v=0 (d) v=0

The equation of refraction at a spherical surface is mu_2/v-mu_1/u=(mu_2-mu_1)/R Taking R=oo , show that this equation leads to the equation (Real depth)/(Apparent depth)=mu_2/mu_1 for fraction at a plane surface.
