Learning Intentions

• You can apply the equation c=ʎv to solve for wavelength and frequency on a quiz.

• You can use the equation E=hv to solve for energy and frequency on a quiz.

• You can describe how the light emitted from excited electrons is used to explore electronic structure of an atom.

• You can improve what ever you struggled with on your quiz.

Content Standards being covered:

Student understand the quantum mechanical atomic model that describes the structure of an atom and changes that can occur to that structure.
62. Max Planck developed the idea of “quanta” - a discrete unit of Energy related to frequency
68. Elements, when excited with enough energy, will emit their own atomic emission spectrum, a unique set of frequencies on the electromagnetic spectrum due to the transition of electrons from a higher to a lower energy state
69. The electromagnetic spectrum is the broad range of frequencies emitted through electromagnetic radiation
70. Electromagnetic radiation moves through space in waves
72. The frequency of a wave is how many complete wave occur per second, is symbolized by ѵ, and is measured in Hertz (Hz= 1/seconds= seconds-1)
73. The speed of light, c, is equal to 3.0 X 10⁸ m/s
74. As wavelength (λ) increases, the frequency (ѵ) of the wave decreases and therefore relate to one another using the equation c= λѵ
77. The frequency of the electron can be related to the Energy of it using the equation E=hѵ (where h= Planck’s Constant= 6.626 x 10^¯34 J s)
