To travel far, you must have high intensity, which a normal torch light does not have to go through like, Marina Tench's depth. So! check the power of your torch light before diving at the great depth.
Since the light goes on diverging (as you know from torch light) therefore the time that it reach the bed, the luminance of the light would get very low, so that is why the light can not travel deeper into the water. But intensity also matters here too. If you have very high intensity light source then you probably don't have to use any further more converging medium but if you use low intensity light source, no matter how much you try to converge it using a medium, it won't show as clear as the high intensity light did.
they travel smoothly
because the water gets deeper. so the swells in the ocean are more frequent but smaller since theres more water
Light can travel through air, water, glass, and any transparent material.
It is possible for a medium itself to travel, but in that case case it isn't called a wave, but a current. For example, water flowing in a river.
Whenever light hits a water surface, some of the light is reflected off, and some of it is refracted, or "bent", deeper into the water. The proportion that is reflected and refracted depends on the wavelength of the light and the angle of incidence. When light goes straight down into the water, most of it penetrates the surface and goes into the water. When the light impacts at an angle, more of the light is reflected away.
An example is that sunlight penetrates sea water for a certain depth. The deeper the sea water the less is the light. This is why at the very deep depths, it is pitch black, as no light can reach this level. Also, if light couldn't pass through water, we would not be able to see the bottom of a swimming pool.
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
they travel smoothly
There are more things for the light waves to bounce off of in water, so light can not travel in a straight line or as far.
The speed of light in water is about 225,400 kilometres per second.
they travel faster. Light waves travel more QUICKLY as they enter water. ^^ whoever done this;; thanks! i really needed the answer....
the darkness and the weather condition
yes they travel faster :)
Has to do with reflected light, its wavelength, and how water effects it. Red light cannot travel as deep in water as green or blue. Therefor, when a red fish goes deeper the needed RED LIGHT cannot reach it and will not be reflected off the fish. SO! It looks black because it is REFLECTING no color. Thats what color is... reflected light.
Since air has a lower optical density than water, light waves can travel faster in air.
Yes, light travels slower in water than in air.
Invertebrates found in the deeper zones of the body of water, usually where there is no effective light penetration.
