Calculate the wavelength, frequency, and wave number of a light wave whose period is `2.0 xx10^(-10) s`.

Explanation

To solve the problem of calculating the wavelength, frequency, and wave number of a light wave with a given period of \(2.0 \times 10^{-10}\) seconds, we can follow these steps:

### Step 1: Calculate the Frequency
The frequency (\(f\)) of a wave is the reciprocal of its period (\(T\)). The formula to calculate frequency is:

\[ f = \frac{1}{T} \]
