Objectives
- Understand the properties and behaviour of waves, including electromagnetic and sound waves
- Use the Huygens-Fresnel principle to describe the reflection of light from a surface, including diffuse and specular reflection
- Use ray diagrams to describe the images formed by a mirror due to the reflection of light
- Use Snell's law to describe the refraction of light through a surface and total internal reflection
- Use ray diagrams to describe the images formed by a lens due to the refraction of light
- Understand the difference between waves and pulses and their properties like wavespeed, amplitude and energy
- Understand the difference between longitudinal and transverse waves
- Describe the properties of periodic waves, including period, frequency and wavelength
- Describe the behaviour of waves at boundaries and how the polarisation of electromagnetic waves influences intensity using Malus' law
- Interpret the electromagnetic spectrum and derive the energy density of electromagnetic waves
- Explain the Doppler effect by analysing sound waves propagating from a moving object
- Understand wave interference and how it results in the formation of beats and standing waves
- Describe the diffraction of light using a single-slit and Young's double-slit experiment, and the influence of diffraction grating
- Understand the phase change of light, and thin-film interference and its applications
Pre Requisites
- Basic knowledge of introductory physics (mechanics)
- Basic algebra
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
