spektral chiziqlar– alohida chastotada nurning emirilishi yoki emissiyasi tufayli spektrdagi bir chiziq.
spectral lines– a line in a spectrum due to the absorption or emission of light at a discrete frequency.
spektrometr–to'lqin uzunligini o'lchash uchun optik qurilma, yorug'lik nurlarining burilishi va prizma yuzlari orasidagi burchakka, ayniqsa yorug'likdan o'tib ketadigan yoriqdan, yorug'likdan chalg'ituvchi yorug'likdan, yorug'likni buzib tashlaydigan prizma va teleskopdan iborat bo'lgan asbob (prizma spektrometeri). Bu shaytonning nuriga qaraladigan va tekshiriladigan nurdir		spectrometer– an optical device for measuring wavelengths, deviation of refracted rays, and angles between faces of a prism, especially an instrument (prism spectrometer) consisting of a slit through which light passes, a collimator, a prism that deviates the light, and a telescope through which the deviated light is viewed and examined.
