But the speed of a wave has nothing to do with the amplitude of its crests and troughs. Speed is measured by the distance the wave travels in a certain amount of time. Specifically, it's measured in meters per second.We already have the 'per second' part down. wave is a disturbance that travels through a medium in a periodic fashion, carrying energy without transporting matter. Waves are described and measured by five wave parameters: the period, the frequency, the amplitude, the wavelength, and the speed.
The biggest part of the brain is the cerebrum. It makes up about 85 % of the brain's weight. Its surface has a lot of wrinkles and cracks. The cerebrum is the thinking part of the brain. It controls your muscles and makes them move when you want them to.When you think hard, try to solve a math problem or draw a picture you use your cerebrum. It is also the area which stores your memory. The cerebrum has two halves.he cerebellum is a lot smaller than the cerebrum and sits at the back of the brain. It's very important because it controls balance, movement and the way your muscles work together. It allows you to stand on your feet without falling down or lets you balance your weight on a surfâ or snowboard.
The hindbrain is made of the cerebellum, pons and medulla. Often the midbrain, pons, and medulla are referred to together as the brainstem. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action.
