The total amount of heat energy received by the sphere of radius r is
Amount of heat energy radiated by unit surface of the sun in the same time workout as Take, R = mean distance of earth from the sun and r = radius of sun
The temperature of the photosphere, referred to as the effective temperature of the sun, is usually taken as
The approximate distribution of the flow of sun’s energy to the earth’s surface is
The solar radiation that is felt at the earth’s surface includes
(i) Direct radiation that has passed through the atmosphere
(ii) Diffuse radiation from the sky
(iii) Absorbed radiation from the water
Identify the correct statement
When the sun lies at a mean distance from the earth, the heat flux from the sun to the outer edge of the atmosphere has been found to be
