The average amount of energy received on a surface perpendicular to incoming radiation at the top of the atmosphere is called (1) Solar radiation (2) Electromagnetic spectrum (3) Solar constant (4) Electromagnetic constant
Assertion (A):Solar radiation first and foremostheats the Earth's surface which in turn determines the temperature of the air above. Reason (R) : Heating of the air determines its stability, which affects cloud development and precipitation.
Fill in the blanks according to the Greenhous effect. "Clouds and gases reflect about ....... a ... of the incoming solar radiation, and absorb some of it but almost .... b ..... of incoming solar radiation falls on Earth's surface heating it, while a small proportion is reflected back."
An earth- orbiting satellite has a solar energy collecting panel with total area 5 m^2 If solar radiations are perpendicular and completely absorbed, the average force associated with the radiation pressure is (Solar constant = 1.4 k Wm^(-2) )
In solar radiation, the intensity of radiation is maximum around the wavelength lambda_(m) . If R is the radius of the sun and c is the velocity of light, the mass lost by the sum per unit time is proportional to
