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.
What happens to white light when it passes through a prism? light rays spread apart, making the image appear smaller What happens to light as it passes through a concave lens? light rays spread apart causing images to appear larger What happens to light as it passes through a convex lens?
