slavikrds [6]

Answer:

5.38035 m

Explanation:

n_w = Refactive index of water = 1.43

h = Depth = 5.5 m

Critical angle is given by

\theta_c=sin^{-1}\dfrac{1}{n_w}\\\Rightarrow \theta_c=sin^{-1}\dfrac{1}{1.43}\\\Rightarrow \theta_c=44.37^{\circ}

d = horizontal distance from the post where she no longer see the bottom of wooden post

So,

tan\theta_c=\dfrac{d}{h}\\\Rightarrow d=tan\theta_c\times h\\\Rightarrow d=tan44.37\times 5.5\\\Rightarrow d=5.38035\ m

The distance d is 5.38035 m
