What is visible light and what portion can humans detect?
Visible light waves are the electromagnetic waves which are detected by the human eye. They make up only a small part of the electromagnetic spectrum. So, visible light is any light in which the human eye can detect.
What is a small star that only gives of faint light and are cool?
That can either be an old white dwarf, a red dwarf. or a brown dwarf.
How do scientist detect heat waves?
Consider a blind person, he cannot see sun but he can tell if he is standing in sun or shade, how? Because he can feel infrared waves heating up his/her skin. Similarly there are certain substances that are sensitive to certain kind of waves, there can be an arrangement to detect these like a circuit to detect radio waves and so on.
What wavelengths can astronomers detect from earth?
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
How many light receptors does the eye have?
There are to types of cells that act as photoreceptors in the eye. The Rod and Cones. Rods detect only the presence or absence of light withough distinguishing between colours thus giving black nad white vision (as at night). Cones detect coloured in the images but are less sensitive, ie they require more light to function.
Can optic nerve impulses only be interpreted as light?
There are two types of sensory receptors: rods and cones. Rods detect light, and cones detect shape.

How can invisible in space be detected?
Visible light makes up only a fraction of the total light, our eyes and internal components have a limited range over which hey can detect light. This is known as the visual spectrum. However, electronic devices (sensors) exist that can detect ranges of light our eyes cannot.
Why do you faint when only when your left arm gets poked with a needle?
that is not the only reason for fainting and most people dont faint from that
Can you kill a Pokémon?
No, they can only faint.
How is Pluto difficult to find?
Pluto is difficult to observe from Earth because it is about 3.66 billion miles away, and only appears as a faint point of light.
What cells of the retina detect light?
the answer is photoreceptors. search photoreceptors to figure out what they are.
Is the only part of electromagnetic spectrum that the human eye detect?
That's the spectral band that scientists have dubbed "visible light".
Can humans detect visible light?
Answer is simply yes , human eyes is only sensitive to the visible light at the electromagnetic spectrum , however there is a different in wavelength and the frequency depending on the color of the visible light
What is the purpose of simple eyes on a grasshopper?
The simple eyes also called ocelli are only used to detect light intensity and not for seeing.
How do you use the word glimmer in a sentence?
Glimmer is a faint glow, or to create a faint light from some source. Metaphorically it refers to a slim chance (glimmer of hope).Examples:A glimmer of light from the shop was reflected in the store window across the street.In the cold desert night, the only light was the glimmer of the stars.When the plane crashed into the lake, there was a glimmer of hope that some passengers survived.
