Waves — Syllabus & Topics

Topics covered in Waves for J&K CET Physics.

Topics in Waves

1

Introduction to Waves and Types

  • A wave is a disturbance that travels through a medium or space, transferring energy without transferring matter
  • Mechanical waves require a medium (sound, water waves, seismic waves)
  • Electromagnetic waves can travel through vacuum (light, radio waves, X-rays)
2

Transverse and Longitudinal Waves

  • Transverse waves: particle motion perpendicular to wave direction (crests and troughs)
  • Longitudinal waves: particle motion parallel to wave direction (compressions and rarefactions)
  • String waves are transverse, sound waves in air are longitudinal
3

Wave Displacement and Parameters

  • Wavelength (λ): distance between two consecutive identical points
  • Frequency (f): number of oscillations per unit time
  • Time period (T): time for one complete oscillation, T = 1/f
4

Speed of Waves

  • Wave speed depends on properties of the medium, not on frequency or amplitude
  • For transverse waves on string: v = √(T/μ), where T is tension, μ is linear mass density
  • For sound in gases: v = √(γP/ρ) (Laplace correction to Newton's formula)
