11tani1=μ=1/sinic
Hope it is correct [1]
if i1,r1,r2 are angle of incidence,reflection and refraction,then calculate critical angle of medium........

11if the ray comes from denser to rarer the ray should bend away from the normal
r1+r2=90
r1=i1
u2/u1=sini1/sinr2=tani1
u2/u1=sinic=tan1
hope this is correct
11eureka, which one is correct? tell us that and then tell thank u[3]
11how machan?
I'm telling that 1/sinic=tani1
And Subash is telling sinic=tani1
11Anirudh at this specify one thing none of the media is air
u in ur soln is the refractive index of which medium i think that will make a difference
3The denser medium have the refractive index μ1 and the rarer medium have the refractive index be μ2
at the crtical angle r2=900 and
from snell's law
μ1sin ic=μ2sin r2
sin ic=μ1/μ2
1/μ=sinic μ2/μ1=μ
