WHY SUN APPEARS RED:
SUNLIGHT CONTAINS 7 COLOURS [VIBGYOR] AS IN THE RAINBOW , OUT OF THESE VIOLET HAS THE LOWEST WAVELENGTH AND RED HAS HIGHEST WAVELENGTH .
IN SUNSET AND SUNRISE THE SUNLIGHT HAS TO TRAVEL MORE DISTANCE , SO AS THE SUNLIGHT TRAVELS MORE DISTANCE THROUGH THE ATMOSPHERE ONLY COLOURS HAVING HIGH WAVELENGTH CAN REACH US
HOW TO MEASURE THE TEMPERATURE OF SUN :
BY MEASURING THE BRIGHTNESS DISTRIBUTION OF THE SUN AND FITTING IT WITH PLANCKS LAW THE TEMPERATURE CAN BE CALCULATED
