what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?

green light has a wavelength of 5200 å. calculate the energy of one photon of green light.
1 amstrong =
10-10
Energy of a photon is given by E =hf,
But we need to find the frequency first
