What is the frequency of a 6.14 x 10^4 m wave

andrew11 [14]

From the information give, I'm going to assume the wave is in a vacuum...

You use the equation: f= $\frac{C}{Wavelength}$ where c is the constant for speed of light ( $3.00 x 10^{8}$

so f= $\frac{3.00x10^{8}}{6.14x10^{4}}$

f= 4.89 x $10^{3}$ Hz (approximately)
