Similarities Between Light and Matter (VCE SSCE Physics): Flashcards

Physical quantities in discrete packets, not continuous values

$p = \frac{h}{\lambda}$

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

Lowest energy state of atom ($n=1$ for hydrogen)

13.6 eV

Discrete lines at specific wavelengths only

Matter/light exhibits both wave & particle properties

Photons carry momentum & have particle nature

Different quantised energy states create spectral fingerprint

Oxygen (green/red) and nitrogen (blue/purple)
