Bonjour

Pouvez vous m'aidez dans ce problème :

For an atmosphere represented by p=p0exp(-z/H)

estimate the ratio of the limb to vertical absorption paths for a
uniformly mixed gas. Assume a tangent height h and derive an
expressionfor the vertical path from the top of the atmosphere
to this tangent height. Parameters you will need are H =7 km,
the radius of Earth R = 6370 km. Plot the ratio of the
slant to vertical paths as a function of h ranging from 20 to 80
km.
si jointe le cours en cas de besoin.

merci beaucoup
