Let's tackle subtraction first. Subtraction in hexadecimal works similar to subtraction in decimal. Let's do a pair of decimal problems and see if we can parallel the solution method in hex. Suppose we want to subtract 1586 - 243 (in decimal).
Refraction of Light Rays. the bending or deflection of light rays as they pass through the various media of the eye that include the conjuctiva, cornea, aqueous humor, lens, and vitreous body.
Important Physical Properties. â¢ Light waves travel in air at a constant velocity. until they penetrate another medium, such as. glass or water, at which point they are suddenly. slowed, causing the rays to bend. â¢ The bending of light waves because of a change. in velocity is called refraction.
