Final answer:
Type II supernovae are produced when the core of a massive star collapses, while Type Ia supernovae occur when a white dwarf accretes enough material from a companion star to exceed the Chandrasekhar limit and then collapses and explodes.
Step-by-step explanation:
The spectra of Type II supernovae would be different from Type Ia supernovae due to the differences in the characteristics of their sources. Type II supernovae are produced when the core of a massive star collapses, while Type Ia supernovae occur when a white dwarf accretes enough material from a companion star to exceed the Chandrasekhar limit and then collapses and explodes.
Type Ia supernovae are brighter than Type II supernovae and can be seen at very large distances. They are found in all types of galaxies and have little variation in their maximum luminosities or in how their light output initially increases and then slowly decreases over time.
On the other hand, Type II supernovae are about 5 times less luminous than Type Ia supernovae and are only seen in galaxies that have recent, massive star formation. They also have a range of peak luminosity values and are less consistent in their energy output during the explosion.
