Answer:
Amplitude is the vertical distance between a ridge and the midpoint of the wave.
Explanation:
A mechanical wave is a disturbance that travels through a material or substance that is a medium of the wave. For example, when a tense string is pressed, the disturbance caused spreads along it in the form of a wave pulse. The disturbance in this case consists in the variation of The Shape of the string from its equilibrium state
it is important to know:
Crest: the crest is the highest point of this amplitude.
Period: the period is the time it takes the wave to go from one point of maximum amplitude to the next.
Amplitude: amplitude is the vertical distance between a crest and the midpoint of the wave.
Frequency: number of times that vibration is repeated.
Valley: it is the lowest point of a wave.
Wavelength: distance between two consecutive ridges of this size.
Transverse wave velocity.-
The propagation speed of a wave on a string (v) is proportional to the square root of the string tension (T) and inversely proportional to the square root of the linear density (μ) of the string:
Answer:
2270 full wavelengths.
Explanation:
The wavelength of the sound wave (assuming sound speed of ) is
.
Now, assuming the distance to the last row is 1947m, the number of wavelengths that fit into this distance are
which is 2270 full wavelengths.
Hence, there are 2270 full wavelengths between the stage and the last row of the crowd.

Answer:
1.Ultrasound is a mechanical wave
2.Ultrasounds are sound waves having a frequency above 20,000Hz
3.ltrasound is not included in the electromagnetic spectrum
4.An ultrasound scan uses high-frequency sound waves to create images of the inside of the body
5.Therapeutic ultrasound has no known harmful effects when done right by your therapist
