Yes, mass never changes. No exceptions.
Mangenese is the element which have 25 protons
Change in energy is E=hc/wavelength of emitted photon
Charge and uncharged particles
Answer: Electromagnetic waves are transverse in nature as they propagate by varying the electric and magnetic fields such that the two fields are perpendicular to each other.
Accelerated charges are responsible to produce electromagnetic waves.
