What are the relationships between the different wave properties (frequency, wavelength, wave speed, period, amplitude)
2 answers:
Answer:
As frequency (cycles per second) increases the wavelength decreases.
As frequency increases the period also decreases
If wave speed or velocity increases, so too does the frequency
Amplitude of a wave is totally independent of frequency, period etc. So it remains the same as frequency shifts. Like FM radio the amplitude remains the same as the frequency of the broadcast modulates.
Explanation:
F= 1/t Frequency is inversely proportional to time (wavelength)
Period is the time it takes for one wave cycle to complete Period is 1/f

vw=λT Speed of propagation vw= wavelength x T time
vw=fλ Knowing frequency multiply times wavelength to get wave speed.

Amplitude varies only as the energy applied varies. Like transmission power, in a 60 hz power feed the amplitude can be 120, 230, 460 volts (note these nominal amplitudes are RMS root mean squared or .707 of the peak of the waveform).

Answer:
The gravitational pull is determined by the mass and distance.
Explanation:
According to Newton's law of universal gravitation
where F is the gravitational pull, G is gravitational constant, m₁ and m₂ are masses of bodies and r is the distance between them.
It can be seen from the above equation that F is directly proportional to the product of the masses and inversely proportional to the square of distance between them.
F ∝ m₁m₂
F ∝ 1/r²
