In the field of acoustical physics the mathematical relationship (wavelength (lambda) = speed of sound (velocity) / frequency (cycles per sec)) indicates that lambda (wavelength) would increase if the speed of sound were increased while the frequency (cps) is held constant (e.g., 100 Hz). Setting aside (for the moment) the empirical issues surrounding how one increases the speed of sound while holding frequency constant, my question relates to understanding the pressure mechanics that would have to underlie such an increase in wavelength. I’m looking for an intuitive physical explanation that starts with the idea that wave length describes the distance required for the pattern of pressure increases (condensation) and decreases (rarefaction) to repeat its self. Doesn’t an increase in wave length mean that somewhere in this process the leading edge of the pressure wave must have selectively and spatially jumped forward relative to the trailing wave? Really ! – How could that happen?
