Answer:

6.37 x 10⁷Hz

Explanation:

Given parameters:

Wavelength = 4.71m

Unknown:

Frequency  = ?

Solution:

To solve this problem, we use the expression below:

           V = F∧  

V is the velocity  = 3 x 10⁸m/s

F is the frequency

∧ is the wavelength

  3 x 10⁸  = F x 4.71

      F  = 63694267.52Hz = 6.37 x 10⁷Hz
