A ray of white light travelling through the air strikes the surface of a sheet of crown glass at an angle of incidence of 38.0°. The refractive indices for crown glass for red and violet light are 1.513
and 1.532 respectively.
a)Which is refracted more, the red or the violet light?
b)What is the angle of refraction for the red light?
c) What is the angle of refraction for the violet light?
d) What is the angle of dispersion? (Angle between the directions in which both lights emerge)​

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the answer is 3.1 his answer is wrong mines is right

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
