A lower energy photon will have a longer wavelength.

Here's why:

1. The energy of a photon is given by the equation E = hv, where E is energy, h is Planck's constant, and v is frequency.

2. According to this equation, if the energy (E) decreases, the frequency (v) must also decrease because h (Planck's constant) is a constant value.

3. The speed of light (c) is given by the equation c = λv, where λ is wavelength and v is frequency.

4. If the frequency (v) decreases (as we established in step 2), the wavelength (λ) must increase in order for the speed of light (c) to remain constant (since the speed of light is also a constant value).

So, a lower energy photon will have a longer wavelength.
