Question

how can you find the Frequency if you only have the wavelength? can you solve this example what is the Frequency of the wavelength 4km? can you please show your steps thanks.

Answer 1

75000 Hz

Step-by-step explanation:

f = V / λ (f= frequency, v=velocity of wave, lambda= wavelength)

alternatively, f = c / λ (f= frequency, c= speed of light- 3.00x10^8 m/s, lambda= wavelength)

f= [3.00x10^8 m/s]/[4000 m]

=75000 Hz
