Presentation on theme: "Frequency & Wavelength"— Presentation transcript:

1 Frequency & Wavelength
Unit 5 Chapter 20 … Section 2

2 Frequency & Wavelength
Warm-Up Frequency & Wavelength Textbook p. 594: #1, #2, & #3 (Passage-1) and #1 & #2 (Passage-2)

3 Frequency & Wavelength
definition (review): the distance from any point on a wave to an identical point on the next wave use the Greek symbol lambda

4 Frequency & Wavelength
definition (review): the number of waves passing a given point in an amount of time (per 1 second) measured by Hertz (Hz) units use an “f” symbol

5 Wave Speed (v) velocity (speed) = wavelength x frequency
Frequency & Wavelength (v) velocity (speed) = wavelength x frequency Remember the Boyles & Charles Laws? Indirect relationships and Direct relationships

6 Frequency & Wavelength
Practice Frequency & Wavelength Guided and Student practice: Textbook p. 582: “Math Focus” All: Determine the wave speed of a wave that has a wavelength of 5m and a frequency of 4Hz. Students: work on Q’s #1 & #2

7 Frequency & Wavelength
Exit Ticket Textbook p. 583: answer these four questions (10 pts) #2 (1 pt.) #4 (3 pts) #5 (3 pts) #6 (3 pts)
