This question is about waves and wave properties.
By making reference to waves, distinguish between a ray and a wavefront.
The diagram below shows three wavefronts incident on a bounda
CHAPTER 1. SIMPLE HARMONIC MOTION
Examples of Simple Harmonic Motion
Simple harmonic motion appears in a wide variety of physical systems.
When a system is displaced from a stable equilibrium, the restoring force
is usually proportional to the disp

Problem 3 Light of wavelength 633 nm is incident on a narrow slit. The angle between the first diffraction minimum on one side of the central maximum and the first minimum on the other side is 1.20. What is the width of the slit? A
This chapter deals primarily with sound waves.
The most common questions relate to the Doppler Effect.
Speed of Sound
The speed of sound is not a constant. It travels at different rates depending on
the density and temperature of the substanc
