Question

please help me in this ,thank you!

5. You are looking, from directly above, at a goldfish at the bottom of a 34.0-cm fish tank filled with water. How far away does the fish look to you? The index of refraction of water is 1.34.

Answer 1

Let us conocen the diagram. Here due t refraction of x 1 light from ad lense medium for rare medium, the fish at o approy at appears at A. 17

| Raya A on our age can't follow! the carve path of 1oo logs our eye s the the fish at A. say, 6 AO wales u Bed OF = Real depth of the fish d=34cm. Now, due to refracton, apparant depth fish as do AB Rn. of the own and for ege We know that if we place the object denne medain and cal rare medier medium, then refractive endex of dense medium seal depth d M= apparent depth Here, the dease medium is water with refractive index M= 1.34 a 1.34= 22 34 d 1-39 2 DR 1.39 25 37 cm 12 25 So, the fish is now reen at a=25.37 am depth from the tebe level of water. Ain (Apparent depth)
