Tonn dhamhnach
Is cuid lárnach de theoiric na meicnice chandamach iad 
 tonnta damhnachaí, mar shampla de dhéacht toinne is cáithnín. Taispeánann gach damhna iompar cosúil le tonn. Mar shampla, is féidir leictreonléas a díraonadh díreach cosúil le tonn solais nó tonn uisce. I bhformhór na gcásanna, áfach, tá an tonnfhad róbheag le tionchar praiticiúil a bheith aige ar ghníomhaíochtaí ó lá go lá.

Mhol an fisiceoir Francach Louis de Broglie an coincheap go n-iompraíonn damhna mar a bheadh tonn ann sa bhliain 1924. Tugtar hipitéis de Broglie air freisin .  Tugtar  tonnta de Broglie  ar thonnta an damhna.

Is é tonnfhad de Broglie an tonnfhad, λ, a bhaineann le cáithnín ollmhór (ie, cáithnín le mais, seachas cáithnín gan mhais) agus tá baint aige lena mhóiminteam, p, trí tairiseach Planck, h :
