Wavefront Builder

Wavelets grow from every point. Build the new wavefront and bend it.

Physics · Class 12 · Light as a wave · 8 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Into the glass: In a medium, f stays and λ shrinks
  2. Water to glass: From one medium to another: λ₁μ₁ = λ₂μ₂
  3. Wavelets grow: Huygens: every point on a front is a new source
  4. Twice as far: The front's shape sets how fast light fades
  5. Bend by wavelets: Refraction by wavelets
  6. Through the layers: Through flat layers, μ sin θ stays the same
  7. Glass wedge: A wedge holds back one side of the front
  8. Graded glass: Optical path bends the front
