A guitar string has a length of 0.40m and is held fixed with both edges under tension. When it’s plucked, it oscillates with a fundamental frequency of 300 Hz. What wavelength does the wave on the string have?

Is the working just meant to be L=wavelength/2 (the fundamental frequency formula), so 0.8m?

And also, to convert from photons.cm^-2.s^-1 (photons per square cm per second) to photons.m^-2.s^-1 (photons per square m per second), would you convert from cm to m or square cm to square m? Would I divide by 100 or 10000 essentially?

Thanks in advance
