Hi students, in this question, a coin is being placed at the bottom of a beaker which has got two sides taken as x and y.

And in this case, the value of x is taken to be 5 .49 centimeter, while the value of y is taken to be 5 .88 centimeter.

Now, in this question, we are asked to find out the speed of light in this particular liquid, which is taken a small letter v.

And here in this figure, you can see that the critical angle c will be equal.
00:30
To the angle of incidence i therefore in such case the value of angle of incidence i can be found out using the equation tan inverse of x divided by y and here in this equation by substituting the value of x and y we get i to be equal to tan inverse of 5 .49 divided by 5 .88 which on simplification gives the value of angle of incidence i to be equal to 4 .4.

43 .03 degree.

Next we have to find out the value of refractive index mu of this particular liquid.

And this can be found out using the snl's law...
