g current (AC) Lenses PHYN LOOn W in the solenold, then what in the total magetie What is the tux theough a single winding of the the flux through " single winding. There i t light the sotemoid. (Min: the indurtauce of «, current 1 4.0 A is flowing , then ight (freqiency 1-5.00× 10". Hz) travels in inediun. #1. It then strikes aelivn in given by LN thaough tho solenoid is Ne, where N in the Orange I the interface with medium 2 and undergoes refraction. You measure the speed of the light in each inedium and find that it travels at 0.800c in medium #1 and n seconds, and between times 120 0.007e in medium number e) What is the speed of the light in ench medium in m/st (2 marks) 2. (b) What is the wavelength of the light in each medium? ( marka) (c) What (d) If the angle of incidence between the two media was ,-16r, then what was the angle of transmission? (2 marks)Explanation / Answer
(A) v1 = 0.8 x 3 x 10^8
= 2.4 x 10^8 m/s
(B) v2 = 0.667 x 3 x 10^8 = 2 x 10^8 m/s
(C) n1 = 1/0.8 = 1.25
n2 = 1/0.667 = 1.50
(D) n1 sin(theta) = n2 sin(theta2)
1.25 sin(16) = 1.50 sin(r)
r = 13.3 deg
