Course Description

The aim of this subject is to introduce the concept of waves in physics and their applications. To begin with, simple harmonic motion is introduced for the purpose of demonstrating the relationships between the two types of motion in terms of their mathematical functions. Overall, the syllabus comprises mechanical waves, both transverse and longitudinal waves, and electromagnetic waves, which covers the wave theory of light. The phenomena of superposition and interference for these types of waves are carefully discussed and illustrated. The topics in optics also include some selected optical instruments like lenses and spherical mirrors.

Course Learning Outcomes

1 ) Explain the concepts, laws and theories in simple harmonic motion, waves and optics
2 ) Justify scientific investigations in areas of simple harmonic motion, interference of waves (mechanical and light), diffraction, derivation of some laws in waves and optics (reflection and refraction of light).
3 ) Evaluate qualitative and quantitative of scientific problems based on the concepts, laws and theories in simple harmonic motion, waves and optics.

 Frequently Asked Questions

A1 : Optics is the study of light and its uses. "Light" is electromagnetic radiation which can be detected by our eyes, ie electromagnetic radiation with wavelengths in the range ~400 nm - 700 nm (though often very similar ideas apply beyond both ends of this wavelength range).
