a string that is stretched between fixed supports separated by 75.0 cm has resonant frequencies of 420 and 315 hz, with no intermediate resonant frequencies.what are (a) the lowest resonant frequency and (b) the wave speed?



Answer :

To get the resonant frequencies of a single cohesive wave, just use formula v = f.The wave velocity is denoted by the letter "v," while the wave's distance is denoted by the symbol "."

The length of the string:

L=75.0 cm=0.75 m

The two resonant frequencies:

450 Hz Λ 308 Hz

a) f1=142 Hzf1​=142 Hz

b)v=213 msv=213 sm​

What has the lowest frequency and lowest magnitude among the following?

Gamma rays often have the greatest frequency, while radio waves typically have the lowest.

Is the lowest frequency the first harmonic?

The fundamental frequency is the lowest frequency that can be produced by a certain instrument.A first harmonic of a instrument is another name for the fundamental frequency.
