Electromagnetic Radiation (Grade 10 NSC Matric Physical Sciences): Flashcards

Discrete packets/bundles of energy in EM radiation

$h = 6.63 \times 10^{-34}$ J·s

$E = hf$

$E = \frac{hc}{\lambda}$

$3 \times 10^8$ m·s⁻¹

Joules (J)

Higher frequency → higher energy photons

Shorter wavelength → higher energy photons

Very energetic (high frequency radiation)

Less energetic (low frequency radiation)
