  Transverse waves ↔️ Perpendicular to propagation

  Longitudinal waves ↔️ Parallel to propagation
• Light waves are transverse waves with oscillating electric and magnetic fields perpendicular to their propagation direction.


  True
• Longitudinal waves are waves in which the particles oscillate parallel
• Arrange the following characteristics of waves based on whether they apply to transverse or longitudinal waves.

  1️⃣ Direction of Oscillation: Perpendicular to propagation (Transverse)

  2️⃣ Direction of Oscillation: Parallel to propagation (Longitudinal)

  3️⃣ Presence of: Crests and troughs (Transverse)

  4️⃣ Presence of: Compression and rarefaction (Longitudinal)

  5️⃣ Examples: Water waves, light waves (Transverse)

  6️⃣ Examples: Sound waves, P-waves (Longitudinal)
• The particles in a longitudinal wave move back and forth in the same direction as the wave's movement.
