## Phase Velocity of a Wave (Wavelength, Period)

` $$ \class{blue}{ v_{\text p} } ~=~ \frac{ \class{red}{ \lambda } }{ T } $$ `

Learn how light can be described as a ray or wave and how you manipulate light with lasers and optical lenses.

` $$ \class{blue}{ v_{\text p} } ~=~ \frac{ \class{red}{ \lambda } }{ T } $$ `

` $$ v_{\text p} ~=~ \lambda \, f $$ `

` $$ \frac{1}{f} ~=~ \frac{n_{\text L} - n_{\text M}}{n_{\text M}} \, \left( \frac{1}{R_1} - \frac{1}{R_2} \right) $$ `

In this video, Young's double-slit experiment with light is explained in a simple way. How the interference pattern of the double-slit is formed and which role light diffraction plays.

` $$ \Delta s ~=~ \left( m - \frac{1}{2} \right) \, \lambda $$ `

` $$ \Delta s ~=~ m \, \lambda $$ `

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.

` $$ \Delta s ~=~ \frac{x \, g}{a} $$ `

Here you will learn the basics of geometrical and wave optics. With this you can describe the behavior of light of our everyday life.

` $$ \class{blue}{ v_{\text p} } ~=~ \frac{\omega}{k} $$ `

` $$ f ~=~ \frac{ b \, g}{ g + b } $$ `

` $$ c_{\text m} ~=~ \frac{c}{n} $$ `
