WebSome definitions ¶. The irradiance or radiant flux E is defined as the energy (Joules) crossing a unit surface (1 \ (m^2\)) in unit time (1 second) so it has units of \ (W\,m^2\). To measure it, you could use a photo diode to count the number of photons per second hitting a sensor, recording the wavelength of each photon. The steradian (symbol: sr) or square radian is the unit of solid angle in the International System of Units (SI). It is used in three-dimensional geometry, and is analogous to the radian, which quantifies planar angles. Whereas an angle in radians, projected onto a circle, gives a length on the circumference, a solid angle in steradians, projected onto a sphere, gives an area on the surface. The …
Webis the flux per unit solid angle per unit projected area of the source or surface. The projected area is the projection of the area onto a surface normal to the direction of view and is equal to the actual area times the cosine of the angle between the surface normal and the direction of view. Radiance can vary with position on a surface, and
WebCorrect option is B) The S.I unit of solid angle is steradian, or square radian (symbol: sr ).
