What makes this a wave?
The rope is made up of strands of cotton threads which are braided together
it has a repeating pattern with a specific wavelength, frequency and amplitude.
the rope stops moving when the students stop shaking it up and down.
the student can change the distance the rope moves by moving the rope further up or down
Waves that carry the most energy are the waves that--
move into a new medium
are closest together
move the most slowly
have the greatest amplitude.
Which of the following provides an example of sound waves being reflected?
Hearing music being played by a neighbor's stereo through a wall.
Water in a glass vibrating because of the sound of thunder
a noise that produces an echo when in bounces off a distant wall.
The sound of a distant train getting louder as it approaches an observer
Geologists can learn about rock layers beneath the surface of Earth using sound waves. They use a vibration truck to send sound waves into the ground. A measuring truck as special microphones, called geophones, that pick up sounds.
This method for learning about rock layers depends on what characteristic of sound waves?
Sound waves can travel through and reflect off the rock layers
Sound waves require energy, such as electricity to generate them.
Sound waves travel for an unlimited distance from the source that creates them.
Sound waves are absorbed by dense solids and reflect off liquids.
Music studios use "soundproof" recording rooms. The walls of these rooms are designed in such a way that the only sounds that reach the microphones inside the room are sounds from inside the room. The most important characteristic in designing the soundproof room is to create walls that-
Allow communication between people inside and outside the room.
reflect sounds around the room to alter their properties
allow sounds to move easily from one place to another.
absorb sounds and prevent them from passing through.
Automobile engineers create quieter cars and trucks by designing acoustic glass that--
transmits sound.
reflects sounds.
absorbs sounds.
amplifies sounds.
Humans see different colors because our eyes are responding to light that is different in which characteristic?
speed
Amplitude
Angle
Wavelength
A rainbow happens when sunlight passes through water droplets in the air. Which of the following best explains why?
Water droplets of different sizes filter out light of different colors.
Light of different wavelengths is bent at different angles.
Different chemicals in the water get energy and give off light of different colors.
Light of different colors travels at different speeds through different sized water droplets.
If two light waves have different amplitudes, you can infer that the one with a higher amplitude will
be a different color
reflect easier
Be brighter
Be dimmer
The idea that light is not matter is supported by which of the following evidence?
Light bounces off more objects.
Light can be separated into colors.
Light can be absorbed by objects
Light does not have mass or volume.
A student places a pencil in a glass of water and observes that the pencil appears to be broken.
Which of these provides the best explanation for why the pencil appears broken?
The pencil absorbs all the light rays that hit it.
Water reflects light rays way from the pencil.
Light rays are bent by the water in the glass.
the surface of the water reflects light rays.
he distance from Earth to the Moon can be accurately calculated by pointing high-powered lasers onto the Moon's surface. The time it takes for the light to return is used to find the distance. To make this possible, astronauts on the Apollo 11 Moon mission have to place a device on the Moon that would--
store the laser light for future use.
bounce the laser light back to Earth.
allow the laser light to pass through.
change the frequency of the laser light.
Which of the following is the best example of an object absorbing light?
A black sweater in the sun.
A clean window in the sun.
a curved mirror in the sun.
A long shadow in the sun.
The data table provided here shows the speed of sound in air at various temperatures. The data in the table supports the claim for which of the following conclusions?
As the temperature of air decreases, the frequency of sound waves increases
As the temperature of air increases, the frequency of sound waves decreases.
As the temperature of air increases, the frequency of sound waves increases
Solar panels generate electricity using photovoltaic cells that receive sunlight.
To protect these cells from moisture while allowing sunlight to pass through, engineers must design a cover for the solar panel that is--
waterproof and transmits light.
very flexible and reflects light.
stronger than steel and bends light
cold to the touch and absorbs light.
The illustration shows the path of a laser light leaving a laser pointer.
At what point is the laser light being absorbed?

The diagram shows the relative positions of a light source, apple, paper, and person.
The person can't see the apple. Which of the following correctly describes the light interactions taking place in the diagram?
Light is being absorbed by, not transmitted through, the paper.
Light is reflected off the apple, but absorbed by the light source.
Light from the light source is reflected only off the apple.
Light is transmitted through the paper and then reflected off the apple.
A ringing bell makes noise inside a glass jar. Then the air is removed from the glass jar using a vacuum pump. When all the air leaves the jar, the sound of the ringing bell can no longer be heard.
Which of the following best explains why the students can no longer hear the bell?
Removing the air from the jar allows the bell ring only very softly.
The air in the jar provides a medium for the sound to travel through.
The sound in the empty jar is reflected off the inside of the glass sides.
the difference in pressure inside and outside the glass jar is too great.
This table provides simplified data on the relationship between the amplitude of a wave and the energy the wave carries.
