The wavelength of a blue light is 4800 Å. Calculate the frequency and wave number of this light.

Explanation

To solve the problem of calculating the frequency and wave number of blue light with a wavelength of 4800 Å, we will follow these steps:

### Step 1: Convert Wavelength from Angstroms to Meters
The given wavelength is in Angstroms (Å). We need to convert it to meters (m) for our calculations.

1 Å = \(1 \times 10^{-10}\) m

So,
...
