A diver , at a depth of 12m in water ( mu = (4)/(3)) sees the sky in a cone of semivertical angle

A diver at a depth of 12 m in water (mu=4 //3) sees the sky in a cone of semi-vertical angle

A diver at a depth of 12 m in water (mu=4 //3) sees the sky in a cone of semi-vertical angle

A driver at a depth 12 m inside water (mu = 4//3) see the sky in a cone of semi-vertical angle is

A fish which is at a depth of 12 cm in water (mu = (4)/(3)) is viewed by an observer on the bank of a lake. Its apparent depth as observed by the observer is :

For a fish under water, the entire outside view is confined within a cone. Draw an appropriate ray diagram for this and calculate the value of semi-vertical angle of the cone. Refractive index of water =4//3

Water is drpping out from a conical funnel at the uniform rate of 2cm^(3)//s through a tiny hole at the vertex at the bottom. When the slant height of the water is 5 cm, find the rate of decrease of the slant higher of the water. Given that alpha is semi-vertical angle of the cone.

A fish which is at a depth of 12cm in water (mu=4/3) is viewed by an observer on the bank of a lake. Its apparent depth as observed by the observer is …..cm.
