Course: Fundamentals of Optics

Here you will learn how to measure/determine the focal length of a lens using the lens equation.

Here you will learn what optical power is and how it is related to the focal length. You will also learn what diopters are.

What is the wavelength defined and what unit does it have? How can I determine it?

Here you can find out what the phase velocity of a wave is and how you can calculate it using a formula.

Here you will learn how wavenumber is defined, how it can be calculated and illustrated, and how it is related to angular wavenumber.

Here you will learn the definition of the refractive index and how it relates to the speed of light and the wavelength of light.

Learn how constructive and destructive interference results from the path difference and how to mathematically add two sine waves.

Young's double-slit experiment with light. You learn how the interference pattern of the double-slit is formed and which role light diffraction plays.
