Why does a rainbow show colors from reds to violet?
There's a broad band of wavelengths of light coming from a rainbow. They range from wavelengths that are too short for your eyes to detect, all the way to wavelengths that are too long for your eyes to detect. Within that band of wavelengths is the total band that your eyes can detect, and you see them as a spread out display of all the colors that your eyes and brain can work together to perceive.
What advancements have been made to track tornadoes?
The most valuable tool has been Doppler radar, which can detect the rotation of a tornado at a distance, even when rain or the dark of night would hide it from human eyes. Cell phones have also been useful, since they allow storm spotters to call in tornadoes they see when they are away from a land line.
How do bats' night vision work?
Bats don't rely on their eyes when it gets dark, they use echo-location instead. They use ultrasonic sounds to detect where they are going. They make an ultrasonic sound from their mouths and check to see when the pulse returns to them. The quicker it returns, the closer an object is to them.
What eye color did Mae Jemison have?

Why do bats see better at night?
Bats have eyes and can see both at night and during the day using their eyes. However bats do not rely on their eyes at night (in the dark), because they have another sense they use called "echo location" which works better than their eyes.
What can ocelli detect?
Tiny eyes (also called ocelli) that can detect light and dark are located on top of the spiders cephalothorax. They also can detect different wavelengths and intensities of light.
How many eyes do grasshoppers have in all?
Grasshoppers have 5 eyes in all. They have 2 compound eyes to detect movement. They also have 3 simple eyes to sense dark and light.
When was Candle in the Eyes created?
Candle in the Eyes was created on 2002-07-03.
Why can you not see the colour of cars at night?
The retinas of our eyes have rods and cones. Rods detect light intensity, and cones detect color. The cones do not work as well in dark conditions. That is why, for example, a dark blue car will appear black at night.
What is the purpose of compound eyes for grasshoppers?
Compound eyes detect motion, and simple eyes detect light. or The compound eyes are used to "see". The simple eyes are used to detect light intensity.
Why are rods used in dark areas?
be a little more specific. Okay rods contained in the back of your eyes detect brightness while cones detect color. Besides its awkward to have sex in the day
What are the uses of eyes?
To see the beauty of the earth and know what's danger and what's not
How far away can your eyes spot a match being struck in the dark?
About 50 cm
What form of radiation can your eyes detect?
Our eyes can detect radiation of wavelength ranging from 4000 Angstrom to 8000 Angstrom.
What eye cell does not detect color?
The rods in the retina of the eyes are sensitive to low levels of light and movement. The cones are the ones that are sensitive to color and intensity, so the rods do not see color.
What is a sightless fish?
A sightless fish is a fish that lives in a dark cave and the fishes' DNA knows that the eyes are not needed so the eyes go away
What radiation energy can your eyes detect?
