Question

C.G.S. unit of solar constant

Answer 1

Answer:

The value of solar constant in SI system is 1340 watt/m^2

.

Answer 2

Answer:

CGS unit of solar constant is   $erg/s .cm^2$.

Explanation:

The solar constant  ($G_{SC}$ ) is the flux density that measures the average solar electromagnetic radiation  (total solar radiation ) per unit area. It is measured in a plane perpendicular to the rays and is one astronomical unit   (distance from the sun to the earth ) from the sun.

Solar constant has the value 1366W per square metre.

Unit of Solar constant = $W/m^2$

and,

1 joule = $10^7 erg$

1 watt to CGS units = $10^{7} erg/s$

Therefore,

CGS unit of solar constant = $W/m^2=\frac{J/s}{m^2}=\frac{erg}{s.cm^2} =erg/s .cm^2$
