Question

На дне ванночки лежит монета, поверх которой налит слой воды толщиной h=20 см. На монету смотрят сверху вертикально. Чему равна кажущаяся глубина погружения монеты? Показатель преломления воды n=1,33.

Answer 1

Н=h*1/n
H=0.2/1.33=0.15=15см

Answer 2

Calculation of Apparent Depth

To calculate the apparent depth of the coin, we can use the formula for apparent depth in a medium with a different refractive index:

Apparent Depth = Actual Depth / Refractive Index

In this case, the actual depth is the thickness of the water layer, which is given as h = 20 cm. The refractive index of water is n = 1.33.

Substituting the values into the formula, we get:

Apparent Depth = 20 cm / 1.33

Calculating this, we find that the apparent depth of the coin is approximately 15.04 cm.
