Which of the following is incorrect, in reference to, how this diagram should be labeled?
3 is the wavelength, and 1 is the amplitude.
4 is the crest, and 1 is the wavelength.
3 is the amplitude, and 2 is the trough.
The dotted line is the undisturbed level, and 4 is the crest.
Which of the following statements represents the least amount of energy on the visible light spectrum?
The shortest wavelength will produce a greater energy. The color violet produces more energy than the color yellow.
The longest wavelength will produce a greater energy. The color yellow produces more energy than the color violet.
The longest wavelength will produce a less energy. The color red produce less energy than the color blue.
Which of the following best explains the relationship between frequency, wavelength, and energy of electromagnetic radiation as the model progresses from one to three?
The frequency decreases as the wavelength decreases which causes an increase in energy.
The frequency increases as the wavelength decreases which causes an increase in energy.
The frequency decreases as the wavelength decreases which causes an increase in energy.
An x-ray uses a radiation beam to capture an image of various bones in the body. Gamma rays are used to target and destroy certain types of cancer cells. An MRI takes an image of the body using radio waves and powerful magnets without causing using radiation. What conclusions could an engineer have regarding the use of the various parts of the Electromagnetic Spectrum in the Medical Field?
Medical procedures tend to require higher energy levels, especially to destroy cells. The majority of the medical procedures have a low frequency.
Medical procedures tend to require lower energy levels, especially to destroy cells. The majority of the medical procedures have a low frequency.
Medical procedures tend to require higher energy levels, especially to destroy cells. The majority of the medical procedures have a high frequency.
which color of light gets bent the least and therefore has the lowest frequency, and which color of light that gets bent the most and therefore has the highest frequency
the violet color is bent the least and has the lowest frequency, and the red color is bent the most and has the highest frequency.
the violet color is bent the least and has the lowest frequency, and the red color is bent the most and has the highest frequency.
the red color is bent the least and has the lowest frequency, and the violet color is bent the most and has the highest frequency.
the red color is bent the least and has the lowest frequency, and the violet color is bent the most and has the highest frequency
If the laser pointer was replaced with a speaker is there any point in which an echo could be observed?
Point C - the light is reflecting at point C and an echo is a reflection of light so it should be observable at that point.
Point B - the light is reflecting at point B and an echo is a reflection of light so it should be observable at that point.
There is no point in which you can experience an echo because the light and the sound from the speaker are being refracted at all points.
As student is trying to design an artificial eardrum for their science fair project. They made their eardrum hollow to cut down on cost and weight. When they tested how long it took their test subject to hear a beep, they found that their control ear drum made out of wood did better than their created one. The temperature that day was 98°F.
The created eardrum performed worst because sound travels faster in solids due to the small distance between the particles.
The created eardrum performed worst because sound travels slower in air due to the small distance between the particles.
The created eardrum performed worst because sound travels slower through air in high temperatures due to the particles moving slower.
What type of wave is illustrated in the figure above?
longitudinal wave
Transverse wave

An alien is ringing a bell in the vacuum of space.
Which of the following explanations best describes what might occur with the correct justification as to why it might occur?
You could see the bell ring because light is a mechanical wave and does not require a medium to travel while sound is electromagnetic and requires a medium.
You could see the bell ring because light is an electromagnetic wave and can travel without a medium while sound is a mechanical wave and requires a medium.
You could neither see the bell ring nor hear the bell ring because sound and light are both mechanical waves and require a medium to travel.
A student experiences near-sightedness. The student can see up close, but is unable to focus on objects far away.
What type of lens would be used and how would it help the student see the far away object?
Convex lens: This lens will converge the light sooner and focus on the retina of the eye, allowing the student to see the image.
Concave lens: This lens will converge the light sooner and focus on the retina of the eye, allowing the student to see the image.
Electromagnetic waves are described as transverse waves because the vibrations move
back and forth in the same direction that the wave travels
perpendicular (90°) to the direction that the wave travels
like coils along the length of a spring
in compressions and rarefactions
Which diagram correctly represents a light ray reflecting off a mirror?
A
B
C
D
All electromagnetic waves travel at the same speed in a vacuum. This means that RED light waves have LOWER frequencies and…
longer wavelengths than blue light.
higher amplitudes than green light
shorter wavelengths than Violet light
Four students in a science class were asked to draw a model that illustrates a wave with a high pitch. Each of their models are presented to the right. Which of the four models represents the wave with the highest pitch?
Wave A
Wave B
Wave C
Wave D
Who has a better beard M. Newman or Mr. Shackelford?
Newman
Shackelford
