Is this why?

The atoms of each element vibrate at different oscillations. Which means that not all elements atoms vibrate at the same type of light etc. When EM radiation hits the atom, some it it hits the electrons and the energy is transferred into the electron, since the electron has gained energy, it moves to a higher energy level orbit, over time, the electron jumps back to it's original orbit and loses the energy in the form of a photon.

Is that accurate?

This can happen, but actually it's not the main reason. A hot object can emit spectral lines of well-defined wavelength, like you're describing, but most of the light is black-body radiation. It has a continuous range of wavelengths and comes from the thermal motion of the atoms.
