After the administration of justice he directed his organizing activity, as the circumstances demanded, chiefly towards financial questions - the incidence of taxation in the conquered territories,' and the application of the vast resources which poured into the treasury at Medina.
(1) the planes of incidence and reflection are coincident, and (2) the angles of incidence and reflection are equal.
So that, were a glass so exactly figured as to collect any one sort of rays into one point, it could not collect those also into the same point, which having the same Incidence upon the same Medium are apt to suffer a different refraction.
For the period preceding British rule the records have not been so well preserved, but there is ample evidence to show that famine was just as frequent in its incidence and infinitely more deadly in its effects under the native rulers of India.
Differences of refractive index produce their greatest dispersive effects when incidence on the refracting surface is nearly tangential.
