Calculate the wavelength , frequency and wave number of a light wave whose time period is `3 xx 10^(-10)s`.

Explanation

To solve the problem, we need to calculate the wavelength, frequency, and wave number of a light wave given its time period. The time period (T) is given as \(3 \times 10^{-10}\) seconds.

### Step 1: Calculate the Frequency (ν)
The frequency (ν) is the inverse of the time period (T). The formula to calculate frequency is:

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