2 WAVES Regular, Rhythmic disturbance in a field or medium where a transfer of energy occurs

3 WAVE TYPES  Mechanical: needs a medium (example: water waves, sound)  Electromagnetic: Alternating electric and magnetic fields. Does not need a magnetic fields. Does not need a medium ( radio waves, light) medium ( radio waves, light)

4 Wave Motion 1) Longitudinal waves: Vibration is parallel to the motion of the wave. Also referred to as a compression wave.

5 WAVE MOTION 2) Transverse Wave: Vibration is perpendicular to the motion of the wave.

6 What type is each? Sound waves are mechanical waves because they need air to travel in. They are also longitudinal because air vibrates parallel to the direction of the sound.

7 Water waves are mechanical because they need a medium. They are also transverse because the water moves perpendicular to the wave which is moving towards shore.

8 Aurora Borealis is an electromagnetic wave caused by the magnetic field of the earth. It is also a transverse wave they are light waves.

9 TRANSVERSE WAVES Amplitude Crest Trough Wavelength

10 TERMS Pulse – A single wave disturbance Amplitude – Maximum perpendicular displacement Wavelength - Distance between identical points on consecutive waves. Measured in meters. (Lambda λ ) (Lambda λ )

11 Frequency – Number of waves that pass a point per second. Unit: waves/sec or Hertz (Hz) Unit: waves/sec or Hertz (Hz) Period - Time for one wave cycle. Unit: seconds Unit: seconds T = 1/ f T = 1/ f

12 FORMULA!!!!! V = f λ v – velocity (m/s) f – frequency (Hz) λ – wavelength (m) Speed or Velocity of a wave:

13 Sample problems: Ex: The Sears building in Chicago sways back and forth 6 times in one minute. a) What is the period of the building? a) What is the period of the building? b) What is the frequency of the building? b) What is the frequency of the building? T = time/sways T = 60sec/ 6 sways T = 10 sec T = 10 sec f = 1/T f = 1/10 = 0.1 Hz f = 1/T f = 1/10 = 0.1 Hz

14 Ex: A sound wave traveling at 340m/s has a frequency of 1029Hz. What is the wavelength of the sound wave? v = fλ v = fλ 340m/s = 1029Hz (λ) 340m/s = 1029Hz (λ) λ = 0.33 m λ = 0.33 m
