Many times we have seen the sun becoming red or orange with a bright shining color, but have we thought that why this happens? passes through and disintegrates before reaching us
, The range of scatter is not the same for all colours. Light of shorter wavelengths, such as violet, blue, green, and yellow, is scattered more than those of longer wavelength (the distance between two sound waves or waves;) orange and red.
Why is the sun red in the morning and evening, for this we must first know why the sky looks blue during the day..?
At sunset and sunrise, the sun’s rays have to cover a large part of the Earth’s atmosphere. Due to this, Rayleigh scattering (scattering of the smallest particle of light) is maximum. According to physical laws, Rayleigh scattering is least for waves with short wavelength. For this, red light is scattered the least while violet light is scattered the most. This is the reason why we see the sky blue under normal conditions and during day time… though violet color is scattered the most but it cannot be felt by our eyes.
During sunrise and sunset, as mentioned earlier, the Sun’s rays encounter a thick barrier from the Earth’s atmosphere. Blue light although scattered the most doesn’t get much chance to be scattered widely… because it encounters too many obstacles. However, the red color is negligible due to its short wavelength and hence is seen mostly by our eyes during these two periods. This is the main reason why we see red colored sky at sunset and sunrise.
And for these reasons the sky around the Sun turns red. Red wavelengths pass through air more easily than blue ones. When the sun is setting in the west, its light passes through hundreds of miles of atmosphere before hitting the clouds above it – a process that turns the sky extremely red. Simply put, the red sky is due to the Tyndall effect. Is. This means that the particles floating around in the air are scattering the light.
When you look directly at the sun – or other types of bright light such as a welding torch – ultraviolet light floods your retina, literally burning away the exposed tissue. … It destroys the rods and cones of the retina and can create a small blind spot in central vision, known as a scomata.
