A stick immersed in water appears to be bent. A stick immersed in water reflects light rays. These rays and when traveling in water travel in a straight line path but when they go from water to air, they deviate from their path and get deflected away from the normal. When these refracted rays are produced, they appear to meet at point "I" which is higher than the actual point that is 'O'. Therefore, a stick immersed in water appears to be bent due to refraction. (a) Define lateral displacement. (b) What is the cause of the refraction of light? (c) Explain Snell's law. (d) Which quantity remains constant in case of refraction? (e) Light enters from air to a medium 'X'. Its speed in medium'X'becomes 1.5x 10 m/s. The speed of light in air is 3x10 m/s. Find the refractive index of medium 'X'.

Answer:
As you sight at the portion of the pencil that is submerged in the water, light travels from water to air (or from water to glass to air). This light ray changes ...
