Mechanical (sound) waves are unable to travel through a vacuum, such as through space, but radio waves are transmitted to Earth from satellites. How is this possible?
Radio waves are electromagnetic waves.
Satellites are located within our atmosphere.
Radio waves are very high energy mechanical waves.
Radio waves are changed to gamma rays for transmission.
What would happen to the speed of sound travelling through water as it freezes and becomes solid?
The speed of sound should increase as it solidifies.
The speed of sound should decrease as it solidifies.
The speed of sound does not change because the chemical is still H2O.

The hammering on a train track is often heard twice by workers farther down the track; first as the sound travels through the steel and second as the sound travels through the air. This suggests which graph is true?

most amplitude and compression.

least amplitude and compression.

All waves on the electromagnetic spectrum travel at the same speed in a vacuum. The speed of these waves in a vacuum is 3x108 m/s. As the wavelength of a wave doubles, how does the speed and frequency of the wave change?

The speed remains the same and the frequency is doubled.
The frequency remains the same and the speed is doubled.
How are the energy of infrared, visible light and ultraviolet rays related? And why?
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is proportional to its wavelength.
Infrared contains the most energy and ultraviolet contains the least energy. The energy of a wave is proportional to its wavelength.
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its wavelength.
Infrared contains the most energy and ultraviolet contains the least energy. The energy of a wave is inversely proportional to its wavelength.
This graph is accurate because
mechanical waves cannot travel through a medium.
electromagnetic waves cannot travel through a vacuum.
electromagnetic waves move faster than mechanical waves.
mechanical waves move faster than electromagnetic waves.
Compare the sounds produce by wave A and wave B. The human ear would hear
wave A as a louder sound than wave B.
wave A as a higher pitched sound than wave B.
wave A and B with the same pitch, but wave A as louder.
wave B has a louder and higher pitched sound than wave A.
As light travels from air to water to glass, it will refract. The best explanation for this would be
Glass is less transparent than water, which is less transparent than air.
Light will be transmitted into the new medium each time it reaches a boundary.
A light wave reflects off molecules as it travels, this causes the light to bend,
The speed of a wave slows as it travels at different speed in different media.
__________ lenses refract light rays in toward a central point. When this lens is held close to your eye, the image is magnified and right side up.
Concave
Convex
Prismatic
Refractive
A high school website directs parents to not allow student access to blue laser pointers or allow the students to bring them to school. It includes a video describing the danger inherent in the misuse of all laser pointers particularly the blue laser pointer. Why would they claim that blue laser pointers are more of a concern than red laser pointers?
Colored light falls into the visible region and the red light has a smaller wavelength and higher energy than blue light.
The wavelengths and energies differ. The ultraviolet blue light has a larger wavelength and smaller energy compared to infrared.
Both wavelengths fall into the visible light region but blue light has a smaller wavelength and higher energy than red light.
These colors have similar wavelengths but the blue laser light has more energy than red laser light making it more dangerous.
What do we call the distance labeled from A to B and what could we do to the note played on an instrument to change that distance?
From A to B is known as the wavelength and changing the pitch of the note will change its length.
From A to B is known as the amplitude and changing the loudness of the note will change its length.
From A to B is known as the wavelength and changing the amplitude of the note will change its length.
From A to B is known as the wave height and changing the amplitude of the note will change its length.
Looking at waves A and B. Which description correctly describes the waves?
Wave A has twice the energy because it has a frequency twice as large.
Wave A has twice the energy because it has an amplitude twice as large.
Wave B has twice the energy because it has an amplitude twice as large.
Waves A and B gave the same energy because they have the same amplitude.
A friend throws a coin into a pool. You close your eyes and dive toward the spot where you saw it from the edge of the pool. When you reach the bottom, will the coin be in front of you or behind you? Explain.
Behind - when you are outside the water, the image of the coin appears closer than the actual coin.
Behind - when you are outside the water, the image of the coin appears farther away than the actual coin.
In front - when you are outside the water, the image of the coin appears closer than the actual coin.
In front - when you are outside the water, the image of the coin appears farther away than the actual coin.

Which wave diagram BEST represents a dim red sunset on the right side to the light from an intense ultraviolet bug light on the left side?
Why does light refract when it encounters the glass in a lens?
because it speeds up, which causes it to bend
because it slows down, which causes it to bend
because it hits a dense medium, which causes it to bounce off
because it gets absorbed, which causes it to lessen in intensity

In the old west, a cowboy would put their ear on the railroad track to determine if a train was coming. Using this method, they could tell if the train was coming sooner than just listening for the train.
A good explanation for this would be that
sound and vibrations travel faster through gases than solids.
sound and vibrations travel faster through solids than gases.
sound and vibrations dissipate faster in solids than in liquids or gases.
sound and vibrations are more concentrated in solids than in liquids or gases.
How does a concave lens differ from a convex lens?
