### Unit 10: Simple Harmonic Motion and Waves

In this chapter students will learn about conditions necessary for simple harmonic motion. Pendulum, ball and bowl are some basic examples described in this chapter for simple harmonic motion. Students will analyze forces on displaced pendulum. Students will learn about the important concept of Damping and its effect on Simple Harmonic Motion. Damping progressively reduces the amplitude of oscillation.
Wave motion concept is very important. It is beautifully explained in this chapter by examples of rope, slinky spring and experiments with water waves.
Waves are means of energy transfer without the transfer of matter. Students will learn about different types of waves and different parameters of waves. Distinguish between mechanical and electromagnetic waves.
Students will able to define speed (v), frequency (f), wavelength (λ), time period (T), cycle , crest , trough after studying this chapter. Students will able to describe properties of wave such as reflection, refraction and diffraction with the help of ripple tank.
