An interesting question! If there were no visible light, and never had been, then animals like mammals and humans wouldn't have developed eyes during the course of our evolution - because they would have served no purpose. For example, there are several species of blind cave fish that have evolved in darkness over the past several million years. They have no eyes, because there is no light to see in the caves.
Most animals have eyes that work over a pretty similiar band of frequencies. They evolved to have eyes that work over those frequencies because this is the range that is most transparent in our atmosphere. Our atmosphere attenuates frequencies that are substantially higher or lower, so if we "saw" in those bands, we wouldn't be able to see much! The fact that our eyes have evolved to be most useful in the frequencies that are most transparent gives us some confidence that humans evolved here, on THIS planet, in THIS atmosphere.

Visable light has a higher frequency than?
Infrared light.
What wavelength does white light from the sun have?
Visable light, Infra red and uv rays.
What type of energy is visible and caused by vibrations?
visable energy is light such as sunlight, but now sure what energy is both visable and caused by vibrations
Wjy are rocks not always visible?
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.
Is white light in a visable spectrum longer than blue light?
blue light is a part of visible spectra
Where do visable light waves come from?
Visible light wave sources. Light bulbs and stars are good examples.
Is it true or false the longest wavelength of visable light is violet?
It is false.
What makes a star visable?
The light, radiated by the star is absorbed by our eyes.
What would happen if there was no light house along the Konkan Coast?
what happen if there is no light house
What is a range of light frequenies you can see?
On average humans can see from about 400 to 700 which is the span of visable light on the electromagnetic spectum.
What would happen to humans if there was no light?
They would die.
What would happen if there was no shadows?
there would be no light too...
