Question

all the formulae related to intensity, pressure, radiation​

Answer 1

Answer:

Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is I=PA I = P A , where P is the power through an area A. The SI unit for I is W/m2.

Solar radiation pressure at the earth's distance from the sun, may be calculated by dividing the solar constant GSC (above) by the speed of light c. For an absorbing sheet facing the sun, this is simply: This result is in the S.I. unit Pascals, equivalent to N/m2 (newtons per square meter).

Pressure = force/area
