Class10 Physics | Wave Based Phenomena

Schedule

Nov 22 - Dec 5(4 periods)

Content

  • Reflection
  • Refraction
  • Diffraction
  • Polarization

Instructional objectives

  • Understand the term wavefront
  • Describe how waves can undergo:
    • reflection at a plane surface
    • refraction due to a change of speed
    • diffraction through a narrow gap
    • interference of two sources
  • Describe how wavelength and gap size affects diffraction through a gap
  • Describe how wavelength affects diffraction at an edge

Teaching Process

  • Describe Huygens' wavelet construction model
  • Derive laws of reflection using waves
  • Derive Snell's law using waves
  • Show interference of two coherent sources
  • Show relationship between rays and wavefronts

Activities

  • Demonstrate reflection and refraction using ripple tank
  • Look at interference using ripple tank
  • Demonstrate diffraction using a ripple tank and look at how gap size affects diffraction
  • Look at how wavelength affects diffraction
