5.1 – Light and Quantized Energy – Part 3
• OBJECTIVES: Students will be able to (SWBAT)
1. Calculate the energy of a wave
2. Explain how an emission spectrum helps to identify an
elementelement
• 5 lecture/10 reading questions
• 5-sentence summary
Notes: 5.1 – Light and Quantized
Energy – Part 3
Higher frequency = Higher energy
The colors have a specific
wavelength/frequency
VIOLET HAS SHORTEST
WAVELENGTH �
HIGHEST FREQUENCY �
MOST ENERGY
RED HAS LONGEST
WAVELENGTH �
LOWEST FREQUENCY �
LEAST ENERGY
Photon
• A particle of electromagnetic radiation with
no mass and a specific amount of energy
Planck’s Energy of a Photon Equation
• Ephoton = h×ν
– Energy of a photon = Planck’s constant × frequency
