Refraction through a Prism
प्रिज़्म से प्रकाश का अपवर्तन
In Class 12 Physics, this topic from Chapter 9: Ray Optics and Optical Instruments explains how a triangular prism bends light as it passes through its refracting surfaces. Students learn to trace the path of a ray, understand the angle of deviation, and relate the prism’s geometry and refractive index to the condition of minimum deviation. The topic also introduces dispersion, showing why white light separates into its constituent colours, and connects these ideas with optical instruments and familiar observations.
