Draw ray diagram when incident ray falls...

Draw ray diagram when incident ray falls normally on one of the two equal sides of a right angled isosceles prism having refractive index `mu = sqrt3` .

Text Solution

Verified by Experts


` mu = sqrt(3) = (1)/(sin i_c) rArr sin i_c = (1)/(sqrt3)`
` sin c = (1)/(sqrt3) ` which is less than ` (1)/(sqrt2)`
`therefore ` Angle of incidence ` lt i_c`
Total internal reflection takes place.
