Answer 2

Answer:

3.44 × 10^-3 meters.

Explanation:

Given the wavelength w, velocity v and frequency the formula connecting the three is given below :

w = v/f

From the question we have :

Frequency = 100kHz

Given that the frequency is given in kilohertz we need to convert this to Hertz.

We convert this as below :

= 100 × 1000 = 100000Hz

V = 344 m/s

Doing the substitution we have:

w = 344/100000 = 3.44 × 10^-3 meters
