far ultraviolet वाक्य

In elementary science, far ultraviolet light is called " black light " because, while itself unseen, it causes many minerals and other substances to fluoresce.
Far ultraviolet emissions have been detected from this star with the Far Ultraviolet Spectroscopic Explorer, while X-ray emissions were detected with the XMM-Newton space telescope.
In airborne and space-based remote sensing such photon counters are used at the upper reaches of the electromagnetic spectrum such as the X-ray to far ultraviolet.
Apollo astronauts used spectroscopes to study sunlight reflecting off the moon's surface more than 20 years ago, but they didn't take pictures in the invisible far ultraviolet.
In his doctoral thesis, Holweck described a seminal study of soft X-rays, that part of the spectrum of electromagnetic radiation which lies in between X-rays and the far ultraviolet.

There are two maxima of the imaginary component ( the absorptive index ) of water, one at the microwave frequency, and the other at far ultraviolet ( UV ) frequency.
