<p>83.212.232.250: Matter is not only solid</p> <hr /> <div>{{Merge to|Wave-particle duality|discussion=Talk:Wave-particle duality|date=March 2013}}<br /> <br /> In [[quantum mechanics]], a branch of [[physics]], a '''matter wave''' is when you think of [[matter]] as a [[wave]]. The concept of matter waves was first introduced by [[Louis de Broglie]]. Matter waves are hard to visualize, because we are used to thinking of matter as physical object. De Broglie revolutionized quantum mechanics by producing the equation for matter waves.<br /> <br /> == Wavelength of Matter ==<br /> Based on the fact that light has a wave-particle duality, De Broglie showed that matter might exhibit wave-particle duality as well (simply meaning that matter is made of both particles and waves). Basing his formula on earlier formulas, he arrived at the equation below. <br /> <br /> &lt;math&gt;\lambda=\frac{h}{mv}&lt;/math&gt;<br /> <br /> Where [[λ]] is the [[wavelength]] of the object, ''h'' is [[Planck's constant]], ''m'' is the mass of the object, and ''v'' is the [[velocity]] of the object. An alternate but correct version of this formula is<br /> <br /> &lt;math&gt;\lambda=\frac{h}{p}&lt;/math&gt;<br /> <br /> Where ''p'' is the [[momentum]]. (Momentum is equal to mass times velocity). These equations merely say that matter exhibits a particle-like nature in some circumstances, and a wave-like characteristic at other times. [[Erwin Schrödinger]] created an advanced equation based on this formula and the [[Bohr model]], known as the [[Schrödinger equation]]. <br /> <br /> == Related pages ==<br /> *[[Quantum mechanics]]<br /> *[[Wave-particle duality]]<br /> <br /> <br /> [[Category:Wave physics]]<br /> [[Category:Quantum mechanics]]</div>
