The frequency (f) of a light wave is related to its wavelength (λ) and the speed of light (c) through the formula:
f = c / λ
where: f = frequency of the light wave c = speed of light in a vacuum ≈ 299,792,458 meters per second (approximately 3.0 x 10^8 m/s) λ = wavelength of the light wave
Given that the wavelength (λ) is 3.0 x 10^(-9) meters, we can calculate the frequency (f) as follows:
f = 3.0 x 10^8 m/s / (3.0 x 10^(-9) m)
f ≈ 100,000,000,000,000 Hz
So, the frequency of the light wave with a wavelength of 3.0 x 10^(-9) meters is approximately 100 terahertz (THz).
