🔹 What is a Wave?
A wave is a disturbance that transfers energy from one place to another without transferring matter.
🔹 Examples of Waves
• Water waves
• Sound waves
• Light waves
• Radio waves
🔹 Types of Waves
1️⃣ Transverse waves – vibrations are perpendicular to the direction of movement
Example: Water waves, light waves
2️⃣ Longitudinal waves – vibrations are parallel to the direction of movement
Example: Sound waves
🔹 Key Terms to Know
• Wavelength (λ): distance between two crests
• Frequency (f): number of waves per second (Hz)
• Amplitude: maximum height of a wave
• Wave speed (v):
👉 v = fλ
*🧠 Think About This:*
Why can sound travel through air but not through a vacuum?
