Orange light of wavelength 6600 Å travelling in air gets refracted in water. If the speed of light in air is `3xx10^(8)ms^(-1)` and refractive index of water is 4/3, find : (i) the frequency of light in air, (ii) the speed of light in water, and (iii) the wavelength of light in water.

Explanation

To solve the problem step by step, we will find the frequency of light in air, the speed of light in water, and the wavelength of light in water.

### Given Data:
- Wavelength of light in air, \( \lambda = 6600 \, \text{Å} = 6600 \times 10^{-10} \, \text{m} \)
- Speed of light in air, \( c = 3 \times 10^8 \, \text{m/s} \)
- Refractive index of water, \( \mu = \frac{4}{3} \)

### Step 1: Find the frequency of light in air
