WGU questions and answers 2024\2025 A+
Grade
Wave
- correct answer A repeating disturbance that transports energy from one place to another is called a
Hint, displayed below
Mechanical wave
- correct answer 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
- correct answer 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
- correct answer have the longest wavelengths of all EM radiation, lowest frequency, lowest energy of all
EMs
Microwave
- correct answer 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
- correct answer (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
- correct answer 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
- correct answer (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
- correct answer have wavelengths that are shorter than UV rays but longer than gamma rays.
-have higher frequencies and higher energies than ultraviolet radiation.
Gamma wave
- correct answer 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
- correct answer 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
- correct answer the oscillation is parallel to the direction the wave is traveling.
-speaking on the mic, clapping, music woofers
