Because the source of light is the sun, which is UP!
You seem to be talking about a light wave. If you increase the amplitude the light gets brighter, and if you decrease it gets dimmer. Amplitude has no effect on colour.
Ponds can be any depth, there is no regulation or even average.
The depth in the ocean is measured by sounding using echo-sounders. Nowadays satellites are also used for this purpose.
Most microscopes do not use a 30x eyepiece because higher magnification can lead to a decrease in image brightness and clarity due to the limited amount of light entering the eyepiece. Additionally, higher magnifications can amplify optical aberrations and reduce the depth of field, making it harder to focus on specimens. Most standard microscopes are designed for optimal performance with lower magnifications, typically around 10x to 15x eyepieces, which balance detail and usability effectively.
decrease;males as they age
It is a 45% decrease
false, the temperature increases with depth
Yes, a groove will decrease the effective diameter of the drum, but not by twice the depth of the groove. Instead, the reduction in diameter is equal to the depth of the groove, which is subtracted from the original diameter. Therefore, the overall decrease in diameter is exactly equal to the depth of the groove, not doubled.
Dissolved oxygen typically decreases with depth in natural water bodies. This is because oxygen levels are influenced by factors such as photosynthesis, surface aeration, temperature, and organic matter decomposition. As depth increases, less light penetrates to support photosynthesis and oxygen consumption from organic matter decomposition exceeds oxygen production.
The depth of field decreases.
The sun can't reach the thermocline layer to heat that depth of water

yes
the more you go down the denser the water gets until the water is so dense that the sunlight can't reach the bottom of the ocean.
The depth of field decreases as one moves to higher magnifications with a microscope. This is because higher magnifications result in a narrower focal plane, making it more challenging to keep objects in focus across different depths.
it increases
The decrease of light intensity on an LDR will cause the resistance of the LDR to increase, which will result in a decrease in current flow through the circuit. As a result, the ammeter reading will decrease.
