Question

One of the lines in the emission spectrum of sodium has a wavelength of 590 nm what is the frequency of the line?

Answer 1

my teacher Mr. burns changed 590 to 590x10 with the exponent of -9 m

Answer 2

yes because 590 NANOmeters is 590*10^-9 meters

Answer 3

ok.

Answer 4

\[c=f\lambda\]
\[f = c/\lambda\\
\quad= \frac{3.00\times10^8\,\text m/\text s}{590\times10^{-9} \,\text m}\\
\quad=\frac{3.00}{590}\times10^{8-(-9)}\,/\text s\\
\quad=\]
