By definition, the word "visible" means something you can see. Beware: you cannot see a light ray or beam or photon as it whizzes past you. You only see those rays that enter your eye. In a dusty atmosphere you might say you can see a light beam, but what you see is that part which is scattered into your eyes.
On average humans can see from about 400 to 700 which is the span of visable light on the electromagnetic spectum.
visable light is what we can see because we cant see radio waves, micro waves, ultra violet, infa red, x-ray or gamma rays
Of course 'TRUE'
infraviolet
No, that's not true. It's the other way round - light from the object hits our eyes. We see the light that enters our eye.

Yes.
the part of the moon cycle when you would not see it is called the new moon.
some rocks are not always visable becasue it depends what the rock is made of. if it is a material of granite then it would be harder to see in the light since granite is a light sort of colour but if it is something like slate which is a darker colour it will blend in with the light on a dull day. so rocks are not always visable depending on the material and light in the day.
everything emits light that we see around us in everyday life. The amount of light it emits determines what 'colour' it appears to be to our eyes. Which is why in pitch black we dont see any colours....no visable light is being reflected off surfaces.
there both in the electro magnetic spectrum. the visable section is the colours we see and there are 3 other types on each end. the spectrum is : Radio waves Micro waves ( funnily enough they are used in microwaves) Infra-red radiation Visable light ultraviolet x-ray gamma ray
You can usually see them when they have a bowel movement.

True. The light you see from the sun is 8 minutes old. The nearest star, other than the Sun, Proxima Centauri. The light you see is 4.22 years old!
YES. Visible light is the leading cause of death of humans on the Earth and is extremely dangerous. THIS IS IMPORTANT. If you see visible light in the wild, DO NOT APPROACH IT. I am the administrator of the Organization for Protection Of Humans from the Dangers of Visible Light (OPOHDOVL). Always remember to watch out for visible light in the daytime. That's when they get you!
yes, it is true. "the reflection you see in a mirror depends on how the surfave reflects light." Quote from a life science book
