If this is supposed to be the wavelength and not the number of photons then you need a space between 2 and meters. There’s always a space between numbers and units (even if the unit is abbreviated). There’s no space for something that modifies the number, like %, ‰, °, k, m, etcetera.

No its a singular 2 Meters wide photon
