Audible frequencies have a range 40 hertz to 30,000 hertz. Express this range in terms of
(i) period `T`
(ii) wavelength `lambda` in air, and
(iii) angular frequency,
Given velocity of sound in air is 350 m s`""^(-1)`

Explanation

To solve the problem step by step, we will express the audible frequency range of 40 Hz to 30,000 Hz in terms of period \( T \), wavelength \( \lambda \), and angular frequency \( \omega \). The speed of sound in air is given as 350 m/s.

### Step 1: Calculate the Period \( T \)

The relationship between frequency \( \nu \) and period \( T \) is given by:

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