Why do you use a lamp to shine on the fish and not run in the deep sea

If the deep sea is more than 5,000 meters to 6,000 meters below, there are very few fish to survive, some are invertebrates, this type of animal has no eyes, they only rely on the cells in the body to sense the existence of the outside world, so naturally, there are no more lights, they can't see, in the deep sea is to use the lights to shine on the fish and do not run.

Deep-sea fish generally have degraded eyes.

Deep-sea fish are either blind or love light.

Fish that have been in the deep sea for a long time are basically blind. It's not like all of them don't run, but squid and the like run very fast.

That depends on how deep the sea you are talking about

Hehe, many people can't answer your question correctly

Let's put it this way, if the deep sea is more than 5,000 to 6,000 meters below, there are very few fish to survive, some are invertebrates, this type of animal has no eyes, they only rely on the cells in their bodies to sense the existence of the outside world, so naturally, there are no more bright lights, they can't see it, naturally, the problem you are talking about, mine is not felt

If it's just one or two thousand meters deep in the sea, there are also fish, and they are naturally very sensitive to light, and some fish will be very aggressive

If you're talking about fish, it also depends on the depth of the sea, which is written in our 100,000 whys, so you can go and ask about it

Because deep-sea fish are phototaxis, right?

It's useless to shine in the deep sea with a lamp.

Fish have poor eyesight. Or degraded.

The reason why there is no light for a long time.

Blue light does not disturb fish because of its wavelength.

Fishing lamp refers to the night fishing, in order to see the subtle movement of the fish float, it is necessary to use a special lamp to irradiate the fish float to make it visible, in order to accurately judge the fish situation, the lamp used at this time is the fishing lamp.

Professional fishing lights use LED lamps with special light colors, and there are two kinds of blue light and purple light on the market. The principle of this fishing lamp is different from the above, and the special light color can effectively reflect the phosphor at the tail of the fish float.

In the night of clever fishing, it can be seen and scattered.

This principle makes it possible to effectively judge the state of the fish drift without too bright lights in night fishing, and will not frighten the underwater fish and affect the effect of night fishing.

When light enters seawater, it is absorbed and scattered by water molecules and suspended matter, so that the light weakens quickly, and when it reaches a certain depth, the light disappears completely. So the seawater is like a filter, filtering different colors of light, and the deeper it is, the harder it is for the light to pass through. Sunlight reaches a depth of 1 m and disappears by almost half of the time, and nearly 70% at 10 m, so the intensity of light in the sea water decreases with depth with a negative exponential pattern of the natural logarithm e.

Red light disappears quickly on the surface, followed by orange, yellow, and green light. By about 20m, the green light had completely disappeared. The intensity of light in seawater is related to the turbidity of seawater and the amount of suspended matter, in the turbid nearshore seawater, 85 of the light is absorbed within 2 3m of the surface, and in the ocean water, the light is absorbed at a depth of 10m is less than 70.

According to observations with a seawater photometer near the Azores in the Atlantic Ocean, there is still some yellow and blue light at a depth of 500 m, a small amount of purple light at a depth of 1,000 m, and a permanent dark zone without any light at a depth of 1,700 m.

In 1919, the scientist Albert Einstein proposed the general theory of relativity that shocked the world. The general theory of relativity is the cornerstone of modern physics, and its essence is that the rotation of huge objects distorts time and light. This is what we often call space-time warping.

It is possible for space-time distortions to occur in the sea, but for a different reason than when light weakens with the depth of the sea.
