Hi everyone! Im studying chapter 1 (edition 6) and I came across example 1.1 which is calculating the wavelength of light of a known frequency.My question is: which numbers do i plug into the formula for C (the speed of light)? I know its 3 x 10^8 m/s but the example used 2.998 x 10^8 m/s. Is the more precise one better or it doesnt matter? Thanks!
