Electromagnetic Radiation and Its Wave-Like Nature (Grade 10 NSC Matric Physical Sciences): Flashcards

Energy that travels through space as waves

$c = 3 imes 10^{8}$ m⋅s$^{-1}$

$c = f imes lambda$

A quantum (energy packet) of light

EM radiation behaves as wave or particle, not both at once

No medium needed; can travel through vacuum

Accelerating charges

Changing E field makes B field; changing B field makes E field

Perpendicular to each other

Slower in materials than in vacuum
