The drop-off of light intensity with distance is not wavelength-dependent. The inverse square law describes the relationship between the intensity of light and the distance from the source. According to this law, the intensity of light decreases as the square of the distance from the source increases.
Mathematically, the inverse square law is expressed as:
I ∝ 1/d^2
where I is the intensity of light and d is the distance from the source. This relationship holds true regardless of the wavelength of light.
However, it's important to note that other factors, such as absorption and scattering, can impact the transmission of light through a medium. These factors may introduce some wavelength dependence in the overall attenuation of light over distance. For example, certain materials may absorb or scatter light more at certain wavelengths than others, resulting in variations in the effective drop-off of light intensity.
