Answer:
3) Wave speed is directly related to the product of wavelength and frequency.
4) Frequency has a direct relationship to wavelength when speed remains constant
Explanation:
V is the velocity (wave speed)
f is the frequency
the symbol next to the frequency is the wavelength
Velocity is proportional because the wavelength and frequency are multiplying.
It would be inversely proportional when the velocity is the dividend of the wavelength and frequency.
On the second statement, frequency (and wavelength) are directly related/proportional to the speed of the wave.
Answer:
upper part of any wave.
Explanation:
we normally define wave motion in term of movement of particles. compressions and rarefaction. rarefaction particles apart , and same as trough ( part of wave above mean line ).
Answer: An electric charge
Explanation:
Because it is carried by charged particles
It's <span>Argon
about 1% in the atmosphere</span>
