Electromagnetic Spectrum Flashcards
Features of electromagnetic waves
Transverse waves
Wave travel in a definite and unchanging speed
Definite ratio between the magnitudes of electric and magnetic fields
Dual character of the electromagnetic waves
Wave
Particle
Energy of a photon
E= h.f= hc/ wavelength of the photon
