[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.
When an earthquake occurs, it releases energy in the form of seismic waves that radiate from the earthquake source in all directions. The different types of energy waves shake the ground in different ways and also travel through the earth at different velocities. The fastest wave, and therefore the first to arrive at a given location, is called the P wave. The P wave, or compressional wave, alternately compresses and expands material in the same direction it is traveling. The S wave is slower than the P wave and arrives next, shaking the ground up and down and back and forth perpendicular to the direction it is traveling. Surface waves follow the P and S waves.
