New cards
Electromagnetic spectrum (low → high energy)
Radio → Microwave → Infrared → Visible → UV → X-ray → Gamma
2
New cards
Formula with wavelength (λ) and frequency (ν)
c = λν (c = speed of light = 3.00×10⁸ m/s)
3
New cards
Formula for energy
E = hν = hc/λ (h = Planck’s constant = 6.626 x1034 J*s)
4
New cards
What increases energy
Higher frequency; shorter wavelength
5
New cards
Emission
Excited atom releases photon → colored line
6
New cards
Absorption
Atom absorbs specific λ → dark line
7
New cards
What each element has
A unique spectrum
8
New cards
Bohr model
Electrons jump between fixed energy levels; ΔE = Efinal – Einitial = hν
