The wavelength of yellow light in vacuum is 6000 Å. If the absolute refractive index of air is 1.0002, then calculate the thickness of air column which will have one more wavelength of yellow light than in the same thickness of vacuum.

Explanation

To solve the problem, we need to find the thickness of the air column that will have one more wavelength of yellow light than in the same thickness of vacuum. Let's break down the solution step by step:

### Step 1: Understand the Given Data
- Wavelength of yellow light in vacuum (λ₁) = 6000 Å (angstroms)
- Refractive index of air (μ) = 1.0002

### Step 2: Calculate the Wavelength of Yellow Light in Air
The wavelength of light in a medium can be calculated using the formula:
