A scientist observes visible radiation from changes in atoms and gamma radiation from changes in nuclei. A separate experiment shows that absorbing radiation changes an atom. Which conclusion is supported by all these observations?
Changes can emit a range of radiations, and absorption can also cause changes.
Changes can emit a range of radiations, but absorption cannot cause changes.
Changes emit only visible radiation, and absorption can also cause changes.
Changes emit only gamma radiation, but absorption cannot cause changes.
