Integrated Physical Science Vocabulary C165 WGU, Top Exam Questions with accurate answers, graded A+ Wave - -A repeating disturbance that transports energy from one place to another is called a Hint, displayed below Mechanical wave - -can travel only through matter. In other words, they require a medium to transport the energy of the wave. (ocean & sound waves, vibration) Electromagnetic wave - -do not require a medium to transport the energy of the wave. They can travel both through matter and through a vacuum (in the absence of matter.) An electromagnetic wave is a combination of an oscillating electric field and an oscillating magnetic field. (EM radiation, light, photons) Radio wave - -have the longest wavelengths of all EM radiation, lowest frequency, lowest energy of all EMs Microwave - -have wavelengths that are shorter than those of radio waves - have higher frequencies and energies than radio waves, but lower than those of infrared radiation. Infrared wave - -(IR) has wavelengths that are longer than those of visible light, but shorter than those of microwaves. -frequencies are higher than those of microwaves, but lower than those of visible light. -Although we cannot see this radiation, we can feel it through our skin as heat. Visible light - -is a very small portion of the EM spectrum. It includes all of the wavelengths of light that the average unaided human eye can detect. Ultraviolet wave - -(UV) has wavelengths that are just shorter than those of visible violet light, but longer than those of X-rays. -The greatest source of UV radiation on the earth is the sun. -Ultraviolet radiation is invisible to the human eye. However, some insects, birds, and reptiles can see it. X-ray - -have wavelengths that are shorter than UV rays but longer than gamma rays. -have higher frequencies and higher energies than ultraviolet radiation. Gamma wave - -are produced in nuclear reactions and explosions of giant stars -have the shortest wavelengths and highest frequencies and energies of all EM radiation. Transverse wave - -the oscillation is perpendicular (to the direction the wave is traveling. -shorter wave lengths -Light waves, vibrations, ripples on a surface of water, x-rays, audience, electromagnetic waves Longitudinal wave - -the oscillation is parallel to the direction the wave is traveling. -speaking on the mic, clapping, music woofers Wavelength - -Horizontal distance between the crests or between the troughs of two adjacent waves. - it is the color of the wave Frequency - -the number of oscillations the wave makes in a given amount of time. -The number of wavelengths that pass by a given point each second Period - -interval in time after which the motion of a particle on the medium starts to repeat. Compression - -the particles are pushed closer together part of the longitudinal wave that is pressed together Expansion - -the particles are pulled away from each other. part of the longitudinal wave that is expand
