Waves

Wave motion, wavelength, frequency, wave speed and superposition.

1.Introduction to Waves

A simple explanation of what waves are and how they transfer energy without transferring matter.

2.Types of Waves

Understand mechanical, electromagnetic, transverse and longitudinal waves in an easy way.

3.Transverse Waves

Learn about waves in which particles vibrate perpendicular to the direction of wave travel.

4.Longitudinal Waves

Understand waves in which particles vibrate parallel to the direction of wave motion.

A beginner-friendly explanation of how waves move through a medium and carry energy.

Learn what wavelength means and how it is measured in different types of waves.

Understand frequency as how many waves pass a point in one second, with simple examples.

Learn what amplitude is and how it tells us about the strength or loudness of a wave.

Study how fast a wave travels through a medium and use the simple formula speed = frequency × wavelength.

10.Period of a Wave

Understand the time taken for one complete wave to pass a point.

11.Superposition of Waves

Learn how two or more waves combine to form constructive or destructive patterns.

12.Interference

Beginner-friendly explanation of constructive and destructive interference of waves.

Understand how beats are formed when two waves of slightly different frequencies overlap.

14.Reflection of Waves

Learn how waves bounce back when they hit a barrier or surface.

15.Refraction of Waves

Simple explanation of how waves change direction when they enter a different medium.

16.Diffraction of Waves

Understand how waves bend around edges and spread out through openings.

Learn the idea of resonance and why objects vibrate strongly at particular natural frequencies.

18.Energy in Waves

Beginner-friendly explanation of how waves carry and transfer energy from one place to another.
