Help!!!
 Let’s go over some on the board
Try some more
 Complete the worksheet
 If you don’t get done in class, it is homework
Opener
 Copy question and answers
 As frequency of a wave increases …
 A. wavelength increases and energy decreases
 B. wavelength increases and energy increases
 C. wavelength decreases and energy increases
 D. wavelength decreases and energy decreases
Review
 Extra help on math
 If anyone needs more help I am available after school today
 Turn in first worksheet
 Grading for correctness
Notes
 Energy follows frequency
 Direct relationship (when one increases so does the other)
 We can relate those two and find how much energy is
associated with a wavelength
 E = hf
 E = Energy (Joules = J)
 H = Plank’s Constant = 6.626 x 10-34 Jsec
 f = Frequency (Hertz = Hz)
Worksheet
 Finish the worksheet
 It should be 15 questions
Opener
 Copy question and answer
 What is the frequency of red light with a wavelength of
700 nm?
 (Remember wavelength MUST BE in meters not
nanometers)
