Hello everyone, this is our figure according to question and here in the question it is given there the value of x1 equals to 2 .1 meter, the value of ia is equal to given 1 .2 meter and the value of x2 equals to given 0 .65 meter.
00:17
So here the value of new equals to given 1 .33.
00:22
So here the question consists two parts, part 1 and part 2.
00:26
So for part 1 we have to find the value of distance b.
00:30
So now let's see the answer.
00:31
So from the figure we can see that from triangle a, b, c, we can say that 10r equals to a is divided by x1.
00:45
So after putting the value from here, you will got the value of r equals to, means reflection angle which is equal to 29 .744 degree.
00:55
So now from f, snell's law, which we will apply at point c so therefore from here we will, we will, we will get mu 1 sine i equals to mu 2 sine i so therefore now here we will put the values so the value of mu 1 is 1 .33 multiplied by sine of i which is equal to the value of mu 2 is 1 and here we can as sign 29 .7 4 4 degrees so therefore from here we will get the value of i equals to 21...
