Txoj ntsiab cai hluav taws xob
Hluav taws xob hais txog kev sib kis ntawm lub zog hauv daim ntawv yoj lossis subatomic particles. Lub zog muaj hluav taws xob ncaj qha los ntawm cov hluav taws xob nyob hauv txhua qhov kev qhia.
Cov hluav taws xob tso tawm sab nraud mus rau hauv daim ntawv ntawm electromagnetic tsis thiab cov khoom sib txuam (xws li alpha particles, beta particles, thiab lwm yam). Xov tooj cua vias thiab nthwv dej muaj zog yog ob lub yoj hluav taws xob. Lawv qhov kev faib tawm tau nrawm, thiab qhov kev faib tawm ceev hauv lub tshuab nqus tsev yog tib yam li cov ntsuas hluav taws xob (3 × 10 ^ 8 m / s).
