Electromagnetic Radiation23 Jan Class listSeating Plan As radiations go, what do you think Electromagnetic Radiation is made of?

Electromagnetic Radiation23 Jan Class listSeating Plan Light

Electromagnetic Radiation23 Jan Class listSeating Plan How EM radiation travels As a wave Also like a particle (packets called photons) At 300,000,000 m/s (Universal speed limit) Doesn’t need a medium(material) to travel through.
