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.)

Oh sorry I don't know Latex u is refractive index and 1u2 means refractive index of 2nd medium with respect to 1@Saurabh Patil .

Kalash I respect the way you interpret the equations guw=auw/aug. Or aug/auw but there is a better way to solve such questions.

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

Last thing i want to ask is the answer B then, plz reply saurabhLog in to reply

have i put the equation right saurabh. so the answer is B then i guessLog in to reply

Oh can u please tell me what is guw=auw/aug. Or aug/auwLog in to reply

Log 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 . – Kalash Verma · 2 years ago

Thanks I will use that next time .pls check the sol I gave above.Log in to reply

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

or in other words \(\mu sin(\theta)=constant\) – Tanishq Varshney · 2 years ago

Yep I know its meaning. See above I have written a way check it if its right.Sorry for inconvenience.Log in to reply
