As you go deeper into an aquatic system, the amount of light decreases significantly due to the absorption and scattering of light by water and suspended particles. In the upper layers, especially in the photic zone, sunlight penetrates, allowing photosynthesis to occur. However, below this zone, light diminishes rapidly, leading to darkness in the deeper regions, where only specialized organisms can thrive. This decrease in light affects the types of life forms that can exist at various depths.
The relationship between light and depth is primarily characterized by the way light intensity diminishes as it penetrates deeper into a medium, such as water or the atmosphere. This phenomenon, known as light attenuation, occurs due to scattering and absorption, which cause light to lose its intensity with increasing depth. In aquatic environments, for example, this leads to varying light conditions that affect photosynthesis and the overall ecosystem. Consequently, deeper areas receive less light, influencing the types of organisms that can thrive at different depths.
The region where no light penetrates in an aquatic environment is known as the midnight zone. The mesopelagic zone is an area where small amounts of light penetrate.
The photosphere is the layer in the sun's atmosphere that is dense enough to emit plenty of light but not so dense that the light can't escape. Below the photosphere, the gas is denser and hotter therefore radiates plenty of light, but that light cannot escape from the sun because it is blocked by the outer layers of gas. so you cannot detect light from these deeper layers.Sources: Book The Solar System by Seeds/Backman (7th Edition) P.143
When the laser light reaches the satellite in a ranging system, part of the light is reflected back towards the Earth. By measuring the time it takes for the light to travel to the satellite and back, the distance between the Earth station and the satellite can be calculated with high precision. This helps in monitoring the satellite's position and orbit.

The region where no light penetrates in an aquatic environment is known as the midnight zone. The mesopelagic zone is an area where small amounts of light penetrate.
The region of the aquatic environment where light can penetrate is referred to as the euphotic zone. This zone is characterized by sufficient light for photosynthesis to occur, supporting the growth of algae and phytoplankton that form the base of the aquatic food chain.

if wavelength of light is of order of radii of earth then why it will penetrate deeper in sea?
The photic zone of the aquatic ecosystem tends to have more life, as it is the upper layer of water where sunlight penetrates, enabling photosynthesis. This zone includes the surface waters of oceans, lakes, and rivers, supporting a diverse array of plants, phytoplankton, and various aquatic organisms that rely on these primary producers for food. In contrast, deeper zones receive little to no light, resulting in less biological activity.
Applying mineral oil to an aquatic plant can suffocate it by creating a barrier on the surface of the leaves, preventing gas exchange and blocking light. This can lead to reduced photosynthesis and ultimately the plant's decline or death. Additionally, mineral oil can negatively affect the water quality and surrounding ecosystem, harming other aquatic organisms. It's best to avoid using mineral oil in aquatic environments.
The best aquatic light bulbs for a fish tank are LED lights, as they are energy-efficient, long-lasting, and provide the right spectrum of light for plant growth and fish health.
