Question:
Two equilateral-triangular prisms \(P_1 \)and \(P_2\) are kept with their sides parallel to each other, in vacuum, as shown in the figure. A light ray enters prism \(P_1\) at an angle of incidence π such that the outgoing ray undergoes minimum deviation in prism \(P_2\). If the respective refractive indices of \(P_1\) and\( P_2\) are \(β 3 /2\) and \(β3\), then \(\theta = sin{β1}[\sqrt \frac{ 3}{ 2} sin ( \frac{\pi}{B} )],\) where the value of \(\beta\) is ______.

- A region in the form of an equilateral triangle (in x-y plane) of height L has a uniform magnetic field π΅β pointing in the +z-direction. A conducting loop PQR, in the form of an equilateral triangle of the same height πΏ, is placed in the x-y plane with its vertex P at x = 0 in the orientation shown in the figure. At π‘ = 0, the loop starts entering the region of the magnetic field with a uniform velocity π£ along the +x-direction. The plane of the loop and its orientation remain unchanged throughout its motion.
