    • What do waves transfer in the direction they are traveling?
      Energy
    • How do particles in a medium behave when a wave travels through it?
      They oscillate but stay in the same place
    • What happens when you drop a twig into a calm pool of water?
      Ripples form on the water's surface
    • What are the two types of waves discussed?
      • Transverse Waves
      • Longitudinal Waves
    • What type of vibrations do longitudinal waves have?
      Parallel vibrations
    • How can you measure wave speed?
      Using the formula v =
    • What is the relationship between wave speed, frequency, and wavelength?

      v = fλ
    • What should you fix when investigating waves with a signal generator?
      The frequency on the signal generator
    • What happens to a wave when it hits a boundary at an angle?
      It undergoes refraction
    • How can you visualize refraction using a ray diagram?
      By drawing the boundary and incident ray
    • What is the process of refraction at a boundary?
      1. Draw the boundary and normal line
      2. Draw the incident ray and measure angle of incidence
      3. Draw the refracted ray based on material density
    • What happens to the angle of refraction if the second material is denser?
      It bends towards the normal
    • What is a wave front?
      A line showing points on a wave
    • What occurs when a wave crosses a boundary at an angle?
      Part of the wave front crosses first
    • Why does a wave bend when crossing a boundary?
      Due to differences in speed across the wave front
    • What is the continuous spectrum of electromagnetic waves?
      • Radio Waves
      • Microwaves
      • Infrared
      • Visible Light
      • Ultraviolet
      • X-rays
      • Gamma Rays
    • How are radio waves produced?
      By oscillating charges
    • What are some uses of electromagnetic waves?
      • Communication (radio waves)
      • Cooking (microwaves)
      • Temperature monitoring (infrared)
      • Medical imaging (X-rays)
    • What is a Leslie Cube used for?
      Investigating emission of infrared radiation
    • What should you do before measuring temperature with a Leslie Cube?
      Wait for the cube to warm up
    • What should you ensure when using an infrared detector with a Leslie Cube?
      Position it at the same distance each time
    • What is the risk associated with infrared radiation?
      It can cause burns
    • What precautions should be taken during experiments with boiling water?
      • Be careful when pouring
      • Allow equipment to cool before handling
      • Avoid moving hot equipment
