Lots of things look different under water. As a result of refraction, the light that reaches us from the object under water changes direction.
Refraction
Water and air are different when it comes to light passing through them. This is called refraction.
it is because of Refraction. The speed of light changes in different densities.
Because the reflection of the light up above the shape is seen on the shape. Making it look that colour.
If light diffraction is what you are asking, then the pencil looks a bit broken on the line where it passes from air to water. Also the pencil looks about one third bigger under water.
Go to the Greyhound web site and look it up. There are a lot of different times for travelling from Vancouver and Grand Forks.
3 tuning forks in a circle is Yamaha.
It is refraction caused by light moving at a slightly different speed in water than in air.
Replacement forks for a Harley can be purchased from motorcycle stores, or for more specialised forks, one may wish to look on eBay or a similar site.
sporks, spoons that look like forks
Yes but no , the blue whale is blue & gray but they look a fine lite blue under the sea.
you get water and look at it under a micro scope
Refraction
NO. Exactly the same unless you look at it under a 300x microscope.
Internet :) Look it up on Google or tear into it
There's quite a lot to that, Look up www.parktool.com for instructions.
Subs don't have glass windows to look out of while under-water. The only way crewmen can look outside their sub WHILE UNDER-WATER is by using the periscope.
