the following video is a good introduction to the refraction of light
3d studio of spherical refraction and reflection
This is a good video to start with, it shows the interesting optical effects of spherical lenses
And naturally occurring lenses made from different liquids, shapes ect
these spherical lenses are capable of all sorts of optical effects.
Inverting an image (turning it upside down)
Magnifying an object (enlarge image)
reflect an exterior image (like a curved mirror)
reflect an interior image (like an image object at the outter edge of a sphere)
refract an exterior image (act as a lense with an interior image projection)
refract an interior image (act like a lense with an exterior image projection)
offset apparent position
apparent position ( ə′parənt pə′sishən ) ( astronomy ) The position on the celestial sphere at which a heavenly body (or a space vehicle)
would be.
obscure an object (an object can be hidden in the curvature of a sphere under the correct conditions)
when an object has a near perfect spherical lens around it it can be hidden from view under the correct conditions
