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.
These alternative exercises are better for your back and your physique. A guyâs awareness of his muscles has a simple progression. You start with what you see in the mirror: biceps, chest, shoulders, six pack. You quickly realize thereâs also some interesting stuff on the other side: lats, traps, triceps. At some point, not long after your legs stop growing, you figure out those muscles respond to training, too.
