7th grade science! in what ways are sound waves and electromagnetic waves different? (3 points) they travel at different speeds. electromagnetic waves have frequency but not wavelength. sound waves have frequency but not wavelength. sound waves have wavelength but not frequency.

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
