	ultraviolet radiation – radiation in the part of the electromagnetic spectrum where wavelengthsare just shorter than those of ordinary, visible violet light but longer than those of x-rays.			ultrabinafshali radiatsiya – elektromagnit spektrning radiatsiya qismida to'lqin uzunligi odatiy, ko'zga ko'rinadigan binafsha nurlardan ko'ra, ammo x-nurlari bilan taqqoslaganda ancha qisqa.
	uncertainty principle – the principle of quantum mechanics, formulated by heisenberg, that the accurate measurement of one of two related, observable quantities, as position and momentum or energy and time, produces uncertainties in the measurement of the other, such that the product of the uncertainties of both quantities is equal to or greater than h/ 2 π, whereh equals planck's constant.
