[6 Foods That Are Good For Your Brain] The brain's right hemisphere controls the muscles on the left side of the body, while the left hemisphere controls the muscles on the right side of the human body. When you wink your right eye, that's the left side of your brain at work. Because of this criss-cross wiring, damage to one side of the brain affects the opposite side of the body. In general, the left hemisphere is dominant in language: processing what you hear and handling most of the duties of speaking. It's also in charge of carrying out logic and exact mathematical computations. When you need to retrieve a fact, your left brain pulls it from your memory.
When a wave hits a surface through which it cannot pass through and bounces back what is that called? When a wave hits a surface through which it cannot pass, and bounces back, that is called reflection.
Surface waves are larger in amplitude and longer in duration than body waves. These waves arrive at seismograph after the arrival of P-and S-waves because of their slower velocities. The two different surface waves are: Rayleigh waves or descriptively called ground roll in exploration seismology.
