The name of our project is call observation phenomenon. In our project whe plan to answer a couple of commonly asked questions such as why is the sky blue, why do stars twinkle,where do black holes come from,and what makes up the colors of the rainbow.
WHY IS THE SKY BLUE
Light from the sun or lightbulb looks white but it's really just a mixture of colors. The colors in white light are (ROYGBIV)red,orange,yellow,green,blue,and violet. You can see the colors when you look at the rainbow. The longest wavelength of light is on the red end of the spectrum and the shortest wavelenths are on the blue/violet end of the spectrum. The sky is filled with air. Air is a mixture of tiny gas molecules and small bits of solid sstuff like dust. As the sunlight enters the atmosphere it collids with oxygen and nitrogen atoms. When light hits the gas molecule it may bounce off in a different direction. Therefore the color with the shorter wavelenth is scattered more. Colors such as red and orange pass straight through the air. Since blue is a primary color it's easily activated and seen by our eyes.
WHY DO STARS TWINKLE
The stars are always in the sky. They are always shining during the day,because the sun is bright you can't see them. At night time you can see the stars because the sky is dark. Stars are far away from the earth. Stars really don't twinkle. they look as if they do because from the earth's surface we view the light through thick layers of turbulent air in the atmosphere. Stars near the horizon twinkle more than those overhead because the light passes through more of the atmosphere near the horizon. STELLAR SCINTILLATION
WHAT MAKES UP THE COLORS OF THE RAINBOW
1.sunlight is made up of a range of colors that the eye can detect. the rangeof sunlight colors looks white to the eye. 2.Light of different colors is refracted by different amounts when it passes from one medium into another.
WHERE DO BLACKHOLES COME FROM
THE blackhole is a theoretical entity predicted by the equation of general relativity. A blackhole is formed when a star of sufficient mass undergoes gravitational collapse with most or all of its mass compressed into a sufficiently small area of space causing infinite spacetime curvation at that point. This allows nothing not even light to escape from the event horizon or border.
