You just missed that, in the previous statement, i have referred to this momentum aspect formula (h/lambda) while talking about radiation pressure. I have not seen any reference wherein momentum of photon calculations play any role in ejection of electron..Not to my knowledge, may be you can give some. The color highlighted statement of yours afaik plays no role in electron ejection. Remember one thing Radiation Pressure can be explained classically (by Poynting Vector, Area and Absorption of Energy), and when we talk in QM the cumulative effect of momentum of all the photons do the job, but PEE cannot be explained classically and neither by cumulative effect of photon's momentum. The basic requirement is photon energy > certain minimum value [we don't say, momentum > some value]. So I do not think your reference to momentum in colored line is proper, still I am open you can provide any reference. Moreover by definition photon is quantum of energy, we don't say photon is quantum of momentum.
