A plane wave front of yellow light with wavelength `0.5mum` in air suffers refraction in a medium in which velocity of light is `2xx10^(8)ms^(-1)` them, the wavelength of the light associated with a wave front in the medium would be

Explanation

To find the wavelength of yellow light in a medium where it is refracted, we can use the relationship between the speed of light, wavelength, and frequency. Here’s the step-by-step solution:

### Step 1: Identify the given values
- Wavelength of yellow light in air, \( \lambda_1 = 0.5 \, \mu m \) (micrometers)
- Speed of light in air, \( V_1 = 3 \times 10^8 \, m/s \)
- Speed of light in the medium, \( V_2 = 2 \times 10^8 \, m/s \)

### Step 2: Use the relationship between wavelength and speed of light
