Question

Which of th4 following will likely be totally reflected from the interface? Assume all angles are specified with respect to normal incidence. a) A ray of liglii incident from air to water at 5 degree? b) A ray of light incident from water to air at 5 degree? c) A ray of light incident from air to water at 85 degree? d) A ray of light incident from water to air at 85 degree? e) None of the above Suppose you have a solenoid, which you cut into two parts. The first part has twice the length of the second part. You place these in series in a circuit, so that the current through each is the same. What is the ratio of the energy stored in solenoid 1 (longer solenoid) to that stored in solenoid two (shorted solenoid)? a) U_1/U_2 = 1 b) U_1/U_2 = 1/2 c) U_1/U_2 = 1/4

Explanation / Answer

Option B is correct

because

the critical angle says that the minimum incident angle that

which gives the the light reflected into the same meadia is called critical angle.
