Question

A transparent cube is placed over a printed page. The letters appear at a distance of 2cm from the top of the surface of the cube when seen from above. If refractive index of the glass is 1.5 find the size of the edge of the cube?​

Answer 1

Answer:

The edge of the cube is 6 cm in length.

Hence, when we place the cube on the page, the distance of the letters from the top surface is the real depth of the object i.e., 6 cm.

Now, we know that,

H = Real depth Apparent depth

Apparent depth = Real depth 6 H 1.5 = 4 cm Therefore, the letters will appear at a distance of 4 cm from the top surface of the cube when viewed from above.
