Is it valid to use the small angle approximation in this problem?

Webbthe previous approximations developed by Aki and Richards (1980). They are developed by expanding the Aki-Richards approximation in a power series of the sine of incidence angle. Thus, these formulae are limited from the very beginning to small changes in medium parameters. Wang (1999), on the other hand, starts the whole approach with the exact WebbThe Small Angle Approximation can be applied when θ is small (< 10°), or when d >> D ( much greater - not just a couple times as large, but a few, 10, even 100+ times as large). The angular sizes of many objects in the sky are small and the Small Angle Approximation can be applied when studying them. WebbThese approximations are called small angle approximations, because they are only valid when the angle involved is very small (usually less than about 15 degrees). small heath to dordon
