The mouth of the river is where light penetration is most likely the lowest

The penetration of light into a region of geometrical shadow is called "penumbra." This occurs when only partial obstruction of light causes a partial shadow to be cast.
The thylakoid lumen is likely to have the lowest pH in chloroplasts due to the accumulation of protons during the light-dependent reactions of photosynthesis.
Violet light has the lowest wavelength in the visible light spectrum.
65-35% light penetration.
Assuming you mean visible light, that would be red light.
Red light.
The lowest point on a sound wave is the trough, which represents the lowest amplitude or pressure point in the wave. In a light wave, the lowest point is the trough as well, representing the lowest intensity or energy level of the wave.
photic zone and aphotic zone
As we move from visible light to gamma rays, the penetration depth into our bodies increases significantly. Gamma rays are more energetic and have shorter wavelengths, allowing them to penetrate deeper into tissues and cause more damage compared to visible light. This increased penetration can lead to greater health risks when exposed to gamma rays compared to visible light.
From the items on that list, infrared light has the lowest frequency, and X-rays have the highest.
