Anyone interested in biotech stocks will know that it could be challenging to pick winners in this âhigh risk - high returnsâ industry which is constantly growing and changing. Companies which hit the bullâs eye become overnight success stories with shares even doubling or tripling on positive news.
Particles that are small compared with the light wavelength scatter blue light more strongly than red light. Because of this, the tiny gas molecules that make up our Earthâs atmosphere (mostly oxygen and nitrogen) scatter the blue portion of sunlight in all directions, creating an effect that we see as a blue sky. Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules.
This means that water reflects blue light and absorbs all the rest. Some areas of the sea sometimes appear green but that has to do with how shallow that part is. As you travel deeper under sea you will find that at about 46 meters, most of the blue light is replaced with pitch darkness. Why is the sky blue? The sea and other water bodies are large masses of water contained by catchments in the land whereas the sky is all around us. Even the sky, like the sea appears to be many different shades of blue. You can make this comparison because the same effect that takes place in the sea is what makes the sky blue. The trillions upon trillions of water droplets in the atmosphere reflect the blue wavelength of the sunâs rays while absorbing all the rest.
