What animals use refraction?
bats and dolphins use sound refraction to hunt for food. the bat is blind so they have to use sound refraction.
How does refraction allow you to see?
The refraction of light by the cornea and lens of the eye makes it possible for an image to form on the retina. Without the formation of an image, it would be possible for the retina to detect the presence or absence of light, but not shapes or objects.
What has to be different to allow refraction to occur?
The density. Refraction occurs at the boundary between two media of differing densities, such as air and water.
How does refraction affect the appearance of the sky?
The sky is blue because of refraction. Sunsets and sunrise are so beautiful because of refraction. If there was no refraction, we would see the sky as a black expanse.
What is a good link to see pictures of light refraction?
go to Google, and type in: a good picture of light refraction
How do you use refraction to see?
refrection unit rate
Why can you see your reflection on a shiny surface?
light refraction
How does refraction affect the way you see things?
learn
Does refraction take place in opaque objects?
Refraction is the phenomenon which allows light to pass from one medium into the other. But opaque object will not allow light to pass through. So refraction becomes impossible in case of opaque objects.
Why do you see a rainbow?
We see rainbow due to the refraction of the sun's rays by rain .
Do animals use refraction?
In general, the process refraction only occurs in the eyes (as far as I know). So I assume you are asking how animals use refraction in their eyes, and by "refraction" you mean the refraction of light. In general, when light enters the eyes, it first enters the cornea of the eyes, which is then refracted into the pupil through the aqueous humor. The thickness and convexity of the lens control how the light is refracted into the eye. The light is focused on the retina which has rods and cone (photoreceptors/light sensors) which sends nerve impulses to the brain. Therefore, the animal is able to see. The parts of the eyes that does the refraction are the cornea, aqueous humor, lens, and the vitreous humor. You might want to surf the web for more details about this
