The electromagnetic spectrum is the term used by scientists to describe the entire range of light that exists. From radio waves to gamma rays, most of the light in the universe is, in fact, invisible to us! Light is a wave of alternating electric and magnetic fields.The propagation of light isnât much different than waves crossing an ocean.nother closely related property is wavelength: the distance from the peak of one wave to the peak of the next. These two attributes are inversely related. The larger the frequency, the smaller the wavelength â and vice versa. You can remember the order of the colors in the visible spectrum with the mnemonic ROY G BV.
The lateralization of brain function refers to how some functions, or cognitive processes tend be more dominant in one hemisphere than the other. The medial longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.f a specific region of the brain, or even an entire hemisphere, is injured or destroyed, its functions can sometimes be assumed by a neighboring region in the same hemisphere or the corresponding region in the other hemisphere, depending upon the area damaged and the patient's age.
ABSTRACT-Studies of hemispheric lateralization have identified that certain types of mental processes occur differentially in the left versus right hemispheres or the brain.
