Velocity of light in glass is `2 xx 10^(8) m//s` and that in air is `3 xx 10^(8) m//s`. Calculate the apparent shift of an ink dot covered by a 6 cm thick glass plate.

Explanation

To solve the problem of calculating the apparent shift of an ink dot covered by a 6 cm thick glass plate, we can follow these steps:

### Step 1: Determine the refractive index of glass
The refractive index (μ) of a medium can be calculated using the formula:
\[ \mu = \frac{C}{V} \]
where:
...
