JEE MainPhysicsGeometrical OpticsNumerical+4 / −1
A pole is vertically submerged in swimming pool, such that it gives a length of shadow 2.15 m2.15 \mathrm{~m}2.15 m within water when sunlight is incident at angle of 30∘30^{\circ}30∘ with the surface of water. If swimming pool is filled to a height of 1.5 m1.5 \mathrm{~m}1.5 m, then the height of the pole above the water surface in centimeters is (nw=4/3)\left(n_{w}=4 / 3\right)(nw​=4/3) ‾\underline{\hspace{2cm}}​.
