What they didn't tell you in physics -- in eighth-grade physics -- but they should have, and I wish they had, was that if you multiply the frequency times the wavelength of sound or light, you get a constant.
Ono što vam nisu rekli u fizici -- u fizici za osmaše -- a trebali su -- i ja bi volio da jesu -- jest da ako pomnožite frekvenciju s valnom duljinom zvuka ili svjetla i dobijete konstantu.
