Answer:
Frequency is the correct answer.
Explanation:
When a wave go from one medium to another medium then the velocity, wavelength and Amplitude changes. But there is no change on the frequency.
Here, The string and the surroundings air are two medium , from which the wave travels.
So, the wave has same frequency in both medium.
The correct answer is Frequency.
You've described two (2) axes of motion.
The third one would have been up-and-down.
No.
The acceleration of gravity on or near Earth's surface is 9.8 m/s² ,
not 20 m/s² .
If it were 20 m/s², then you would weigh almost exactly double
what you really weigh now.
Answer:
A) Propagation of pressure fluctuations in a medium
B) air is the medium in which the wave is transported,
Explanation:
Part A.
A sound wave is a longitudinal oscillation of the molecules that forms in a material medium, they can be solid, liquid or gases, therefore the wave propagates in the same direction as the oscillation of the particles.
The most correct answer is:
* Propagation of pressure fluctuations in a medium
Part b
air is the medium in which the wave is transported, otherwise it cannot propagate
