Answer:
λ ≈ 689.66 meters
Step-by-step explanation:
λ = Wavelength (in meters)
c = Speed of light in a vacuum (approximately 3 x 10^8 meters per second)
f = Frequency of the wave (in hertz)
so the problem is, λ = (3 x 10^8 m/s) / (4.35 x 10^5 Hz)
-> λ ≈ 689.66 meters
So, the wavelength of a wave with a frequency of 4.35 x 10^5 Hz is approximately 689.66 meters.
