Step-by-step-Explanation:

Given: A bucket is filled with water upto s height of 36 cm. How much a coin lying at its bottom appears to raised when viewed from outside the water?[Refractive index of water 4/3]

To find: How much a coin lying at its bottom appears to raised when viewed from outside the water?

Solution:

Formula used:

\bold{\pink{Refractive \: index =  \frac{D_{real}}{D_{apparent}}}}\\\\

here

Refractive index of water: 4/3

Real depth = 36 cm

Apparent depth =?

Put the values

 \frac{4}{3}  =  \frac{36}{D_{apparent}}  \\  \\

Cross multiply to find apparent depth to find the coin depth

D_{apparent} =  \frac{36 \times 3}{4}  \\  \\ D_{apparent} = 27 \: cm

The coin raised up = Real depth-Apparent depth

=36-27

= 9 cm

Final answer:

The coin seems to be raised 9 cm up from bottom when viewed from outside.

Hope it helps you.

Answer:

Real Depth=36cm

Apparent Depth=?

Refractive index (n)=4/3

Formula=Apparent depth= Real depth/refractive index

AP=36÷4/3

AP=36*3÷4

AP=27

IMAGE SHIFT=REAL-APPARENT

36-27=9
