Students who only memorize the formula V = lambda x F often believe that the speed V of wave propagation is directly proportional to its frequency F, that is, that if the frequency F of the wave doubles, its speed will double! This video will show that, in fact, the speed V of a mechanical wave and its frequency F are independent of each other. It is worth watching this entire video!
