The most idiotic thing in the solution derived answer is that it shows the refractive index of the liquid to be greater than that of the glass which is the biggest flaw.!!

The solution is violating the very much first required condition that if a beam of light is to be totally internally refracted then the refractive index from which the ray is incident (incidence medium) is to be less than that of the medium into which it is imagined to be entering (to verify the Snell's law offcourse.)

\(\mu\) of glass\(\times sin(\theta_{c})=\mu\) of liquid \(\times sin(90)\)

\(sin(\theta_{c})=\frac{2 \mu}{3}\)

@Tanishq Varshney . My mistake I wrote a solution(nope just a correction).

Oohh sorryLog in to reply

@Saurabh Patil see my way. i=60

Now

Sin60/sin(r) = guo

Or √3/2 = uo/ug Is this the correct way?? Now I think its right sorry @Tanishq Varshney .

@Saurabh Patil .

Oh sorry I don't know Latex u is refractive index and 1u2 means refractive index of 2nd medium with respect to 1Log in to reply

Use the above law directly which would surely give you direct and correct results.

according to snells law \(\mu_{1}sin(\theta_{1})=\mu_{2}sin(\theta_{2})\)

or in other words \(\mu sin(\theta)=constant\)
