Using Sound
100
This type of wave requires matter to carry energy.
What is a mechanical wave only?
100
Any disturbance that carries energy from one place to another through matter and space.
What is a wave?
100
The interaction that occurs when an object takes in a wave as the wave hits it.
What is absorption?
100
Sound waves are produced when something is caused to _______.
What is vibrate?
100
A bat and a dolphin use this to find food and navigate.
What is echolocation?
200
A crowd does this type of wave at a sporting event.
What is a transverse wave?
200
The process to correctly calculate the frequency of a wave.
What is speed divided by wavelength?
200
This occurs when two waves meet and build on each other.
What is constructive interference?
200
A sound wave needs this to travel.
What is any medium?
200
These signals are sent by using a series of zeros and ones.
What are digital signals?
300
Sound wave, Ocean wave, Light wave, and Hand wave are all scientific waves except__________.
What is Hand wave?
300
The speed of a wave with a frequency of 2 Hz and a wavelength of 87 m is this number.
What is 174 m/s?
300
A wave hits an object as shown.
This is an example of _________.
What is diffraction?
300
This feature of a wave can be calculated using the following formula.
number of wavelengths / time
What is frequency?
300
Finley is trying to transmit a sound wave that will travel continuously, but he is frustrated by the excess noise. Finley sending this kind of signal.
What is an analog signal?
400
This wave can travel through space and matter.
What is an electromagnetic wave?
400
The most likely outcome when a sound waves moves from the air through a solid.
What is it will increase in speed?
400
This occurs when two waves traveling along the same medium meet and cancel each other out.
What is destructive interference?
400
As the temperature of a medium increases and the particles bump into each other more often the ______ will increase.
What is the speed?
400
Four patients have been diagnosed with medical issues, ultrasound technology could help all of them but ______.
Who is Josh?
500
Longitudinal waves transfer energy in this direction of the motion.
What is parallel?
500
A higher amplitude of a wave is an indication that it is carrying this.
What is more energy?
500
Plants appear green because they do not absorb the green wavelengths of light. The green light waves do this when they hit a plant.
What is they reflect?
500
Sound waves move faster at higher temperatures and in a solid phase because of these.
What is they carry more energy and the particles are closer together?
500
An ultrasound machine is being used to try to identify potential kidney stones. The machine is working properly; however the sound waves are not able to reflect off an object.
The doctor would tell the patient this.
What is you do not have kidney stones?
