Wavelength. 1  Frequency tells us how many waves are passing a point per second, the inverse of time. 2  Wavelength tells us the length of those waves in metres, almost like a displacement. 3  If we multiply these two together, we are really multiplying 1/s and mâ¦ which gives us m/s, the velocity of the wave!
Best Answer: Connective tissue function:- The cartilage rings support the trachea and prevent it from collapsing when air is taken in. Epithelial Tissue function:- The ciliated epithelium cleans out the particulate material in the air before it enters the lungs.
