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.
Report Abuse. DIFFRACTION-diffraction is bending of light at the corner of an obstacle. eg: DIFFRACTION OF LIGHT REFRACTION-Refraction is the bending of a wave when it enters a medium where it's speed is different.efraction-is the change in direction of waves which occurs when waves travel from one medium to another Diffraction-is the bending of waves around obstacles and opening.
