BVP MedicalBVP Medical 2005

Solution:

The intensity of illumination is given by $ I=\frac{P\cos \theta }{{{r}^{2}}} $ .....(i) where P = power of the source r = distance between source and point $ \theta $ = angle of incidence when $ \theta =0, $ I will be maximum. Hence the rays from the sun .are incident normally on the earth surface.
