True

False??

How does the principle of electromagnetism explain the interaction between earth’s magnetic field and the solar wind?

Great amounts of electromagnetic energy from our sun and other bodies in space travel through space. which is a logical conclusion about these electromagnetic waves? their energy must be very their frequency must be very low these waves can travel without a medium they only travel through a vacuum of space

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
