The number of waves passed in a second

Frequency

The lengths of the wave itself

Wavelength

Energy increases when frequency ____

increases

Energy increases when wavelength

decreases

Speed of Light ( c ) =

Wavelength/Frequency (v)

Frequency (v) =

Speed of light ( c ) / Wavelength

Solving for Energy when given frequency

Energy (E) =2.718 Planck’s Constant (h) x Frequency (v)

Solving for Energy when given Wavelength

Energy (E) = Planck’s Constant (h) x Speed of Light ( c ) / Wavelegnth

Frequency Unit

Hz

Wavelength Unit

Nanometers (Nm)

C → K

K = C + 273.15

K → C

C = K - 273.15

F → C

C = 5/9 (F-32)

C → F

F = (C x 9/5) + 32

F → K

K = (F-32)(5/9) + 273.15
