Two people are speaking to each other from different rooms in a house. They can have a conversation easily, but they are not able to see each other during the conversation.
Why can the people speak to each other without being able to see each other?
Sound waves travel at a greater speed than light waves.
Sound waves can travel a farther distance than light waves.
Light waves are absorbed by air particles, but sound waves are transmitted through the air.
Sound waves are transmitted through walls, but light waves are absorbed or reflected by the
walls.
Satellites use radio waves and microwaves to send and receive information over large distances. Which reason best explains why these are used instead of sound waves?
Radio waves and microwaves can move in the vacuum of outer space.
Sound waves store large amounts of data.
Radio waves and microwaves have the longest wavelengths and greatest energy.
Sound waves are a dangerous way to transfer information.
Read the passage in the image and look at the diagrams.
How can note P and note Q be described, and why?
Note P has a lower amplitude than note Q because the sound vibrations make fewer patterns
in the sand.
Note Q has a higher amplitude than note P because the sound vibrations make more patterns
in the sand.
Note P has a higher frequency than note Q because the space between the sound vibrations
is larger.
Note Q has a higher frequency than note P because the space between the sound vibrations
is smaller.
Why does the student observe that the balloon pops first, and then the popping sound
comes later?
The light waves move faster in air than the sound waves.
The sound waves are reflected by the air particles, but the light waves are not reflected.
The wavelength of sound waves is shorter than the wavelength of light waves.
The sound waves are partially absorbed by air, but the light waves are completely transmitted
through air.
As the tune dial is turned to the right, the oscilloscope attached to the antenna shows
waves closer together. How are the waves changing on the oscilloscope as the radio is
tuned to the right?
The frequency of the waves increases.
The frequency of the waves decreases.
The amplitude of the waves increases.
The amplitude of the waves decreases.
How will the wave patterns on the oscilloscope attached to the speaker change as the
volume changes?
As the volume increases, the frequency of the wave will increase.
As the volume decreases, the frequency of the wave will increase.
As the volume increases, the amplitude of the wave will increase.
As the volume decreases, the amplitude of the wave will increase.
Which pair of points represents one complete wavelength of the wave?
A to C
A to E
B to C
B to D
Read the passage and look at the diagram and table.
Why is 100% of light intensity measured only after passing through air at Location 2?
Air causes the lowest amount of refraction when at Location 2.
Water and glass are more sensitive to changes in temperature.
Water and glass are less able to transmit energy than air.
Air causes more reflection of light when at Location 2.
How does a wireless network function?
The network uses high-speed electrical energy.
The network uses long-wavelength infrared radiation.
The network uses high-frequency radio waves.
The network uses low-amplitude sound waves.
When does an object transmit light?
when the object breaks the light into many pieces
when the object bends the light
when the light stays in the object
when the light passes through the object
If the speed remains constant, which change will double the frequency of the wave?
decreasing W by 1/2
decreasing X by 1/2
doubling the length of W
doubling the length of X
A person wants to redesign a large room in a house to have less echoing of sound and more sunlight. Which design solution will best match the person’s needs?
Hang curtains over the windows that will transmit sound waves and absorb light waves.
Add pillows to the furniture that will reflect sound waves and refract light waves.
Place a thick white carpet on the floor that will absorb sound waves and reflect light waves.
Add a large mirror on the wall that will refract sound waves and reflect light waves.
The distance between which two points represents the wavelength of the wave?
from T to Z
from U to Y
from V to W
from V to X
An ocean wave energy device moves up and down with the motion of an ocean wave. The device produces more energy if larger waves move the device.
Which property of waves does the wave energy device use the most?
amplitude
frequency
volume
wavelength
A student sets up a box with a flashlight that shines on a mirror located at position X.
Other possible locations for objects in the box are labeled A-E.
How can the student place objects in the box to have all the light from the flashlight shine back on the flashlight?
Place a mirror at position E to reflect the light to a prism placed at position C to refract all the
light back to the flashlight.
Place a prism at position E to refract the light to mirrors placed at positions C and D to reflect
the light back to the flashlight.
Place a mirror at position E to reflect the light to a prism placed at position A to refract all the
light to the flashlight.
Place mirrors at positions A and E to reflect the light around the box and back to the
flashlight.
The image shows two ways of transmitting signals for television broadcasting.
Historically, in aerial transmissions for television, the analog signals were transmitted
from a television station tower and received at homes through an antenna. In current
satellite transmissions, the signals are digitized and transmitted from the sender to
the receiver through a satellite.
Why are satellite transmissions used instead of aerial transmissions?
Only satellite transmissions can work in bad weather.
Satellite transmissions can serve a much larger area.
Unlike aerial transmissions, satellite transmissions are a wireless mode of transmission.
Unlike aerial transmissions, satellite transmissions do not have to pass through the air.
A student yells into a cave and hears an echo. What behavior of a wave produces the echo?
The sound wave is absorbed.
The sound wave is refracted.
The sound wave is reflected.
The sound wave is transmitted.
