List of top Physics Questions on Refraction Through A Prism asked in WBJEE

An electromagnetic wave, whose wave normal makes an angle of \( 45^\circ \) with the vertical, is travelling in air and strikes a horizontal liquid surface. While travelling through the liquid, it gets deviated by \( 15^\circ \). If the speed of electromagnetic wave in air is \( 3\times10^8 \text{ m/s} \), then the speed of electromagnetic wave in the liquid will be

Figure shows the graph of angle of deviation \( \delta \) versus angle of incidence \( i \) for a light ray striking a prism. The prism angle is
