Consider an extended object immersed in water contained in a plane trough. When seen from close to the edge of the trough, the object looks distorted because.

A

the apparent depth of the points close to the edge are nearer the surface of the water compared to the points away from the edge

B

the angle subtended by the image of the object at the eye is smaller than the actual angle subtended by the object in air

C

some of the points of the object far away from the edge may not be visible because of total internal relfection

D

water in a trough acts as lens and magnifies the object

To solve the question regarding why an extended object immersed in water looks distorted when viewed from the edge of a trough, we can break down the explanation into a series of logical steps: ### Step-by-Step Solution: 1. **Understanding the Setup**: - We have an extended object placed in water within a plane trough. The observer is viewing the object from the edge of the trough. 2. **Refraction of Light**: ...

Torricelli was the first do devise an experiment for measuring atmospheric pressure . He took calibrated hard glass tube , 1 m in lengt and of uniform cross section , closed at one end . He filled the whole tube with dry mercury taking care than no air or water droplets remain inside the tube , closed the opposite end of the tube tightly with thumb and inverted it . He put this inverted mercury tube into a mercury through , taking care that the end of the tube remains inside the mercury through , An interesting thing was noticed . Mercury in the tube fell down at first and then stopped at a particular position . The height was 76 cm above the free surface of mercury in the through . When the given tube was inclined or lowered in the mercury trough , the vertical haight of mercury level in the tube was always found constant . Torricelli explained this by saying that the free surface of mercury in the trough . Hence , the hydrostatic pressure exerted by the trough measures the atmospheric pressure . If this expriment uses water instead of mercury , then A. length of water will be equal to 76 cm B. length of water will be less than 76 cm C. length of water will be greater than 76 cm D. none of the above
