Question

calculate the wavelength of a photon of blue light whose frequency is 6.3 x 10^14

Answer 1

\[\lambda = \frac{ \nu }{ f }\]

lambda is wavelength
v is speed of light
f is frequency

Answer 2

I plugged in the numbers but it came out as .000000000045. Am I allowed to which the v and f?

Answer 4

i get

0.000000476 which is 4.76 * 10^-7 or 476 * 10^-9 [unit for 10^-9 is nano]

476 nanometers

Answer 5

I got that too but how did you know to make it into 4.76*10^-7?
