  • What are the Learning Objectives of Lesson 7.1 Introduction to Waves
    • Differentiate the longitudinal and transverse waves
    • Identify and discuss the different types of waves
  • Wave
    • a disturbance traveling through medium or in a vacuum
    • it can be described as a disturbance that travels through a medium from one location to another location
  • Wave Pulse
    single unrepeated disturbance
  • wave train
    succession of periodic disturbances
  • Pulse
    a single disturbance moving through a medium from one location to another location.
  • Repeating disturbance
    if we observe that the slinky is continuously and periodically vibrated in back and forth manner, what do u call this?
  • Classification of Waves
    Waves are classified according to their direction of vibration and its nature
    When we talk about nature: it's either mechanical or electromagnetic waves
    When we talk about direction of vibration: It can be either transverse and Longitudinal
  • Mechanical Waves
    type of wave that requires a material medium to propagate
  • Example of Mechanical Wave
    Sound Wave - since it cant travel in vacuum, it needs medium to propagate
  • Electromagnetic Waves
    can travel through a vacuum and in material media such as light, heat, radio waves, and microwave
  • Transverse Waves
    when the particles of the medium are vibrating perpendicularly to the direction of wave propagation.
    made up of alternating hills and valleys
  • Crest
    the top of the hill
  • Trough
    bottom of the valley
  • Rests
    The position of maximum upward displacement from the equilibrium position
  • Trough
    the position of maximum downward displacement from the equilibrium position
