give the definition of the kind of wave motion: compression and rarefraction
Compression refers to the region of a wave where the particles or medium are densely packed or compressed together. In this region, the particles are closer to each other, resulting in a high-density area.
Rarefaction, on the other hand, refers to the region of a wave where the particles or medium are spread apart or more spaced out. In this region, the particles are farther away from each other, resulting in a low-density area.
Both compression and rarefaction are characteristic of longitudinal waves, such as sound waves, where the particles of the medium move parallel to the direction of the wave propagation. In these waves, compressions correspond to the regions of high pressure or maximum displacement, while rarefactions correspond to the regions of low pressure or minimum displacement.
during this wave motion the compression to compression distance is 10 m and take 5 s to move past the same point.
3.41 what s the wavelength of the wave?
3.42 what is the speed of the wave.
sorry this is another question
To determine the wavelength and speed of the wave, we can use the formula:
Speed (v) = Wavelength (λ) × Frequency (f)
First, let's calculate the frequency (f) using the given information that the compression to compression distance is 10 m and it takes 5 seconds to move past the same point.
Frequency (f) = 1 / Time period (T)
The time period can be calculated as the time it takes for one complete wavelength to pass.
Time period (T) = 5 s
Therefore, the frequency (f) is:
f = 1 / T = 1 / 5 = 0.2 Hz
Now, we can find the wavelength (λ) by rearranging the formula:
Wavelength (λ) = Speed (v) / Frequency (f)
For now, the speed (v) is unknown, so we'll need to solve it in the next step.
Now, let's solve for the speed (v):
Speed (v) = Wavelength (λ) × Frequency (f)
v = λ × f
Substituting the given frequency and the calculated wavelength into the equation:
v = λ × f
v = 3.41 m/s × 0.2 Hz
v = 0.682 m/s
So, the speed of the wave is 0.682 m/s.
Lastly, we can calculate the wavelength (λ):
Wavelength (λ) = Speed (v) / Frequency (f)
λ = v / f
Substituting the calculated speed and frequency into the equation:
λ = 0.682 m/s / 0.2 Hz
λ = 3.41 m
Thus, the wavelength of the wave is 3.41 meters.
