Understanding the Relationship
The speed of light in a vacuum (c) is a constant: approximately 299,792,458 meters per second. The relationship between the speed of light (c), frequency (f), and wavelength (λ) is:
c = fλ
Solving for Wavelength
1. Rearrange the equation to solve for wavelength (λ):
λ = c / f
2. Plug in the values:
λ = 299,792,458 m/s / 1.0 x 10^15 Hz
3. Calculate:
λ ≈ 2.9979 x 10^-7 meters
Converting to Nanometers
Since wavelengths of light are often expressed in nanometers (nm), let's convert:
* 1 meter = 1 x 10^9 nanometers
* λ ≈ 2.9979 x 10^-7 meters * (1 x 10^9 nm / 1 meter)
* λ ≈ 299.79 nm
Therefore, the wavelength of the light wave is approximately 299.79 nanometers.
