For particles of very large sizes, scattering can be considered as a result of interference of the rays having multiple reflections and refractions according to the laws of geometrical optics. ... The papers [ 413 , 414 ] presented a method where the scattering field was expressed via the field at the particle surface using the Huygens-Kirchhoff principle, and reflection and refraction laws were employed to find the unknown field (the approach was called physical optics approximation). ...

The length of the shadow depends on the height of an object (like a mountain or a human) and how high up the Sun is. ... We can calculate the length of the shadow if we know the Sun's angle above the horizon and the object's height. ... The Earth spins 360 degrees in 24 hours, which means it spins 1 degree in 4 minutes; that in turn means the Sun moves 1 degree every 4 minutes in the sky. ...
