First you need to calculate the wavelength correctly.I can't make the symbols you did but it is
c = freq x wavelength
3E8 = 5.2E14 x wavelength
wavelength = 3E8/5.2E14 = 5.77E-7 m and that converted to 577E-9 m (or 577 nm). Here is a chart that will show you the color. It's yellow-orange.

You are approaching a stoplight. If the frequency of the light being emitted is approximately 520 THz, what was the wavelength of the light? What color was the light?
v = c/λ
520 THz --> 5.2x10^14 Hz
5.2x10^14 Hz = 3.0x10^8 m/s
λ = 1.56 x 10^23 m
Not sure how to get the color of the light from here.
