Best ResponseYou've already chosen the best response.0v= 2.998 X 10^8 which can be approximated as 3 X 10^8 lambda = 3.10 X 10^14

Best ResponseYou've already chosen the best response.0is that the one ?i thought it was velocity of a wave = frequency x wavelength

Best ResponseYou've already chosen the best response.0You have to use the given formula: \[f=\frac{ v }{ \lambda }\], where f is frequency, v is speed and lambda is wavelength.

Best ResponseYou've already chosen the best response.0No problem. Maybe you did not consider that those figures have exponents. Simply plotting the following in your calculator, you get\[f=\frac{ 2.998*10^{8} }{ 3.10*10^{14} }=9.67*10^{7}Hz\]
