The reflection of a wave is simply a process by which a wave, whether light, sound, infrared, or radio waves, hits an object and bounces off it. But this reflection looks quite different for a mirror than it does for a wall. Law of Reflection. When any wave, including light, hits a surface that is opaque, the light will mostly reflect off that surface. The law of reflection tells us how it bounces off that surface. When a wave is moving toward the surface, it's called the 'incident ray.' When it bounces off, it's call the 'reflected ray.'
Over the years I have met a lot of people in various gyms. Every now and again I would meet some one that would complain about one arm, leg or chest muscle being bigger than the other. In general neither both sides of the human body are equal, and any differences that you see are usually only spotted by yourself.
Common sense tells us a pound of muscle and a pound of fat have to weigh the same, but they do differ in density. This means if you look at five pounds of muscle and five pounds of fat side by side, the fat takes up more volume, or space, than the muscle. Thatâs important when youâre on a diet and part of your goal is the lean look of muscle, not the flabby look of fat.
