Question

A flag is waved 3.2 m above the surface of a flat pool of water. When viewed from under the water, what is the magnification of the flag? Let the indices of refraction nwater = 1.33 and nair = 1.00.

1.33
0.754
1
1.67

Answer 1

1.33

Step-by-step explanation:

For an optical instrument, the magnification ratio of the apparent diameter of the image to that of the object.

Mathematically, from the given information;

Magnification
`= (n_(water))/(n_(air))`

where;

`n_(water) =1.33\\ \\ n_(air) = 1.00`

`= (1.33)/(1.00) \\ \\= \mathbf{1.33}`
