If the energy of the particles come from momentum, I thought mass is needed (as p=mv). How does light carry energy if it has no mass then? (e.g. how does light from the sun warm us?)

Classically, light is a wave and waves can carry energy without having a mass. Its energy depends on the frequency/ wavelength of the light.
