Blue and violet: no these are reflected. Red in much better!
Dark blocks more light because it absorbs the light
White light is all the colors of the light spectrum put together
Prism doesn't add colors to white light, it just dissipate the all colors of white light into different direction. White light contains all seven colors in it. So don't be confused in the addition of colors into white light or dissipation of all colors, containing in white light.
Red
The colours of white light are all of the colors that make up a rainbow. White light is actually a mixture of all colors.
UV light doesn't fully penetrate it. At deepest, it only penetrates less than a millimeter and still doesn't make it past the top layer of skin.
gamma
gamma decay
All the sun's rays penetrate water, but each color penetrates to a different depth. The colors at the upper end of the light spectrum, especially the UV (ultraviolet) that causes tanning, penetrate deepest. The UV portion of the sun's light can penetrate into clear water for a hundred feet or more at midday. The safest way to avoid overexposure is to remember that if you can see the sunlight, it may cause sunburn, and to limit exposure accordingly or perhaps wear a T-shirt or wet-suit.
The colors that are the first to not penetrate are the warm colors like red, orange and yellow. Depending on the depth of the water, green, blue and lastly violet are the most likely to penetrate the bottom of a lake.
Because they need sunlight, which can't penetrate that deep.
The deepest parts of oceans are dark all the time because natural light does not penetrate to the ocean depths. Little is known about life in the depths of the ocean. More is known about the moon than the depths of the oceans. Water pressure is great, the temperature is constant.
blue light penetrates the deepest in water
The deepest tests can be done using x-ray and Ultrasonics. Mag-particle, Florescent Penetrant and eddicurrent are only reliable for surface cracks.
Red light does not penetrate more than gamma rays.
coz it cant
yes it is light and light can
