<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Passage: Wakanga uri mugumisiro wakashata wechiedza chakakurumbira, icho chaida kuiswa kwekuderedza urefu: kuedza kwaMichelsonMorley uye gare garewo kuedza kwaKennedyThorndike. Muchienzanidzo chaicho tsananguro yacho ndeinotevera: Muchimiro chayo chokurara interferometer inogona kuonekwa seyakanyarara mukuwirirana nomutemo wezvokufananidzira, naizvozvo nguva yokuparadzirwa kwechiedza yakafanana mumativi ose. Kunyange zvazvo mufuremu umo interferometer iri kufamba, transverse danda anofanira kuyambuka refu, diagonal nzira pamusoro risingafambi puranga nokudaro achiita nguva yayo rwendo refu, chinhu kubudikidza iyo longitudinal danda zvaizova kunonoka nokutora nguva L c-v L c v nokuda mberi uye reverse nzendo zvichienderana iri kunyange refu. Nokudaro, murutivi rworutivi interferometer inofanira kuderedzwa, kuitira kudzorera kuenzana kwemaawa maviri okufamba maererano nemigumisiro yakaipa yokuedza s. Nokudaro kumhanya kwechiedza kunoramba kuripo uye nguva yokuparadzirwa kworwendo rwokuenda nokudzoka pamwe chete nemaoko eperpendicular e interferometer yakazvimiririra nokufamba kwayo uye mafambiro ayo. Mubvunzo: Ndeipi iri rondedzero maererano nechienzi chakasiyana?  <response>: Muchimiro chayo chokurara interferometer inogona kurangarirwa seyakanyarara mukuwirirana nomutemo woukama, naizvozvo nguva yokupararira yechiedza yakafanana mumativi ose
