Compared to 620 nm photon, a 760 nm photon has ?

There can be two perspectives to use when answering this question. First, let's interpret it through the wavelength. The unit nm is a unit of wavelength. This is the distance from one crest to another of a wave function. Thus, the 760 nm photon has a wider crest than the 620 nm.

Second, let's interpret through frequency. This is the rate wherein one cycle has been completed, which is equivalent to one wavelength. So, the longer the wavelength, the lower is its frequency and vice versa. Thus, the 760 nm photon has a lower frequency than the 620 nm photon.
