visible means we can see light. then why i can only one the walls, why i can not see the path.

that's what.. visible light is the one which you can see on walls.. other lights like infra red and ultra violet, is not visible on walls also.. get me?

Visible light is light you can see as opposed to something like infrared light which you can't see. But you can only see it when it enters your eyes. Light on the way to the wall has not entered your eye, but after it bounces off the wall and comes to you and enters your eye, you can see it. You are not really "seeing" the wall, you are only seeing the light that has bounced off the wall. If the only light in the room were infrared, then the room would appear totally dark to you. There would be infrared light bouncing off the wall and entering your eye, but since you can't see infrared, you can't see the wall and the room would just look totally black to you.

"The visible spectrum (or sometimes optical spectrum) is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. There are no exact bounds to the visible spectrum; a typical human eye will respond to wavelengths from 400 to 700 nm, although some people may be able to perceive wavelengths from 380 to 780 nm. "

I have no idea what you're asking... but here's what I do know on visible light:
When we see white things, we are essentially seeing light for what it is--a reflection of all visible colors in the electromagnetic spectrum. When we see say, "the wall" so as you've put it, we're looking at a reflection of the light that the wall emits to our eyes. There are atoms within the paint upon the wall, and atoms within the wall itself responsible for the characteristic color our brains identify the wall having, so it all stems from there.
Just know that without light, we wouldn't be able to see at all. Light is basically what is responsible for us to see things within space. We are able to see light itself, but what we see when we observe colored objects is the reflection of certain COLORS of light within the white light, (Red, Orange, Yellow, Green, Blue, Indigo, Violet, and all other colors inbetween). Seeing each one of those colors would mean seeing a reflection of the particular one we observe (i.e., "That box is blue because blue light is being reflected to my eye), and the absorption of all other colors.
To make the spectrum simplier, we say that the three primary colors of light are red, blue and green (absorption of these three would produce black; reflection of all three would produce white, i.e., "white LIGHT"). Therefore, the colors from the white light which are absorbed for the blue to be the only color reflected would be the red and green.
Hope I answered your question...

The electromagnetic spectrum is something that is more familiar than one might think. The light that our eyes can see is actually part of the electromagnetic spectrum. This visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow - from reds and oranges, through blues and purples. Each of these colors actually corresponds to a different wavelength of light

Visible light is simply the portion of the electromagnetic spectrum that we as human beings are able to see. Other types of light include infrared and ultraviolet.

Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light) or, in a technical or scientific context, electromagnetic radiation of any wavelength. The elementary particle that defines light is the photon.

you can see the path if the light is bright enough,,,,think of a flashlight with new batteries or the big spotlights at car dealerships or fairs , etc,,,,,even some laser beams are visible,,,,non visible light is like infrared or even night vision is (light enhancing),,,,it has to do with the density and the color scope

Hi. Visible light is detected by your retina. The actual beam is not.
