Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves are ...

Photons are odd little beasts. They can act like waves. They can act like particles. They are teeny tiny messengers of force. They are carriers of energy. If you're enjoying this article, consider ...

We can also use wavelengths to calculate refractive index. By substituting \(v_{1}=f\lambda _{1}\) and \(v_{2}=f\lambda _{2}\) into \(n=\frac{v_{1}}{v_{2}}\) then ...
