electromagnetic radiation
Electromagnetic radiation
  • James Maxwell’s theory
  • all radiation wave-like electric and magnetic fields in space

Electromagnetic radiation

  • waves varying in length

10-14 m - 104 m

  • constant velocity in a vacuum

3 x 108 ms-1

waves
Waves

Waves can be described by their wavelength, frequency

and velocity.

Wavelength, l (m or nm; 1 nm = 10-9 m), the distance between

two identical points on adjacent waves.

Frequency, f (or) n (s-1 or Hz), the number of waves per second

Velocity, c (ms-1 ), the distance a wave travels per second

c = l x f (n)

Wavenumber, 1/l (m -1 or cm -1 ), the number of waves in one metre or one centimetre.

Quanta – small bundles or packets of energy.

- fixed size so transfer of energy occurs in fixed amounts

Electromagnetic radiation is also regarded as a

stream of particles – photons (wave-particle duality).

Energy of radiation for a photon can be calculated using

h is Planck’s constant = 6.63 x 10-34 Js

or E = h c

l

E = h f

(E = h n)

For one mole of photons

E = L h f or E = L h c

l where L is Avogadro’s constant

(E = L h n)

The energy of radiation is calculated in Jmol -1 or kJmol -1
