What is the frequency of a wave with a wavelength of 6.40x10^4 meters?

frequency = 0.47*10⁴ Hz

Explanation:

Given dа ta:

Wavelength of wave = 6.4 * 10⁴ m

Frequency of wave = ?

Solution:

Formula:

Speed of wave = wavelength * frequency

Speed of wave = 3 * 10⁸ m/s

Now we will put the values in formula.

3 * 10⁸ m/s = 6.4 * 10⁴ m * frequency

frequency = 3 * 10⁸ m/s / 6.4 * 10⁴ m

frequency = 0.47*10⁴ / s

s⁻¹ = Hz

frequency = 0.47*10⁴ Hz

Thus the wave with wavelength of 6.4 * 10⁴ m have 0.47*10⁴ Hz frequency.
