(a) If the tension of the two waves is the same, the wave with higher frequency will be the wave with smaller mass per unit length.
(b) The frequency of a wave is inversely proportional to the wavelength of the wave.
The frequency of a wave in string is given as;
f ∝√T/μ
where;
Thus, if the tension of the two waves is the same, the wave with higher frequency will be the wave with smaller mass per unit length.
The relationship of wavelength and frequency is given by the following formula;
f = v/λ
where;
Thus, the frequency of a wave is inversely proportional to the wavelength of the wave.
