Question
Light travels from medium 1 into medium 2, as Light shown. When it hits the boundary of medium 3, it undergoes total internal reflection, as shown. Rank the index of refraction in each medium. n_1 > n_2 n_3 n_1 > n_3 > n_2 n_2 n_1 > n_3 n_3 > n_1 > n_2 n_3 n_2 > n_1 Rank the speed of light in each medium. v_1 > v_2 > v_3 v_1 > v_3 > v_2 v_2 > v_1 > v_3 v_3 > v_1 > v_2 v_3 > v_2 > v_1 A loop of wire (with a battery) is placed inside another loop of wire (with no battery). At time 0, the switch is closed, and a clockwise current begins flowing in the inner loop. What is the direction of the induced current in the outer loop immediately after time 0? Clockwise Counterclockwise Zero What happens if I pick D? What is the direction of the induced current in the outer loop after the current in the inner loop reaches a constant value? Clockwise Counterclockwise Zero I'm curious, but not curious enough to actually pick this one What is the direction of the magnetic field at the center of the loop (after the current reaches a constant value)?

9.Option C is correct
When light passes from rarer to it bends towards normal
If it is denser to rarer bends away.
When light passes from denser to rarer at angle greater than critical angle, it will totally reflected back into same denser medium.
10. Velocity of light in denser medium is less.
Hence option D is correct.
Refractive index= velocity in rarer medium/ velocity in denser medium
11. Counterclockwise direction option B is correct. Here when current is increasing in inner circuit the magnetic field increases and directed inwards. Therefore the current induces in counterclockwise direction to oppose external change.
12. Zero current in outer circuit since there no change in flux with time when study state reaches.
13. Option A is correct. Use Maxwell's corkscrew rule.
