With my job to make the country more frequently. One of the things I like the most is when the country. Blue skies during the day. Gold and black trim with the stars sparkle in the night. That can not be seen if in Bangkok, but was! Ever wondered why the sky is blue during the day and black at night preface why the sky during the day, it is blue, why not be black in the universe is black (actually, it's also a conclusion together. What color is the universe), like the night. ito Many people might say it's daytime, it is illuminated by the sun. It is not as black as night. ito But if it was like that. Why daytime sky is not as white as the sun that time, it was a puzzle for a long time as well. Since the turn up the sky for the first time. It is a question that remains in the brain. Our species so long Until the lapse of time, the 19th century physicist John Tyndall called the iris can explain. Why is the sky blue color. The scientific theory called the phenomenon Calendar Goodall (Tyndall Effect) that the scattering of light pulses. Better than the wavelength of light When reflecting particles suspended in a liquid.
This image will be seen The right hand with the use of laser Pointer 2 glasses slip right through the water. Is invisible laser beam passing. The glass on the left is the water with suspended sediment laser runs runs reflecting particles suspended in the water, the light will be scattered reflected in our eyes can see red streaks on the atmosphere, the atmosphere is provided. The gas molecules (small particles) and ice, dust, ash, salt spray (this group is large particles), especially near the surface. Particles in the atmosphere, the density of light is a form of energy that travels as waves (radiation), for example, the sound is vibration of air. The light is a wave vibration of the electric and magnetic fields (called. Electromagnetic waves, ito electromagnetic waves Space travel at a speed of 299,792 km / sec speed is called the speed of light) rays of light have different energies depending on the wavelength (wavelength) and frequency (frequency) peak wavelength is the distance between two points. (Crest on the top, on the bottom, it is best measured against the bottom) frequency is the number of waves in 1 second means. Radiation whose wavelength is very low frequencies. And has little power In contrast, Short wavelength radiation is high. And have more energy The light we see is white. Light through a prism, if Be looked into as many colors as purple ito and red are the real wave.
