- A man standing on a beach can see the top of a lighthouse 25 km away. If the eye of the man is 1.5 m above sea level, then determine the height of the lighthouse above sea level considering earth’s curvature and refraction correction.The tip of a tower of 210m height is just visible above the horizon from an observer with an eye height of 1.35m. What is the distance between the tower and the observer considering curvature and refraction?In the Newton's Rings apparatus, the light of 615nm and convex-planar lens of radius of curvature 5.6cm are used. When a an unknown liquid is introduced into the air space between the lens and the plate, the diameter of the 13th dark ring is 0.560mm. Find the index of refraction of the liquid. State your answer to the nearest 0.0001.
