Mechanical Waves and Sound
==========================

This chapter covers the properties and behavior of waves and sound.

Key Concepts:
-------------
- Types of waves (transverse, longitudinal)
- Wave speed, frequency, and wavelength
- Sound waves
- Superposition and interference

Sample Question:
----------------
A wave has a frequency of 500 Hz and a wavelength of 0.68 m. What is its speed?

.. math::
   v = f \lambda = 500 \times 0.68 = 340\ \text{m/s}
