Geometric optics includes: The effects of media on the path of light When light bounces back from an object, this is known as: Reflection In reflection, the light rays that hit the object or interface between media with different indices of refraction are called: Incident rays In optics, a medium (or media, plural) is: An object through which light passes When light passes through a transparent medium, it may travel straight through (Transmission or its path may be altered. This altering or bending property of a medium is known as: Refraction The ray of light that enters a transparent medium is termed: Incident ray If light passes through a lens and the rays are spread apart on exiting, this is known as: Divergence If light passes through a lens and the rays are bent toward each other on exiting, this is known as: Convergence A comparison of the speed of light in air to the speed of light through a substance is: IR (Snell's Law) The denser the substance, the more slowly light passes through it, and: The higher the IR The IR of crown glass is:
