listen to the pronunciation of spec.tra (spek'trı) i., fiz. tayf, spektrum
التركية - الإنجليزية
{ç} spectrum
spec.tra (spek''trı) i., fiz. tayf, spektrum
A range; a continuous, infinite, one-dimensional set, possibly bounded by extremes
spec.tra (spek''trı) i., fiz. tayf, spektrum
Specifically, a range of colours representing light (electromagnetic radiation) of contiguous frequencies; hence electromagnetic spectrum, visible spectrum, ultraviolet spectrum, etc

Current 3G technologies can send roughly 1 bit of data - a one or a zero - per second over each 1 Hz of spectrum that the operator owns.

spec.tra (spek''trı) i., fiz. tayf, spektrum
The pattern of absorption or emission of radiation produced by a substance when subjected to energy (radiation, heat, electricity, etc.)
spec.tra (spek''trı) i., fiz. tayf, spektrum
Of a bounded linear operator A, the set of scalar values λ such that the operator A—λI, where I denotes the identity operator, does not have a bounded inverse; intended as a generalisation of the linear algebra sense
spec.tra (spek''trı) i., fiz. tayf, spektrum
{n} an image, visible form
spec.tra (spek''trı) i., fiz. tayf, spektrum
broad range of related values or qualities or ideas or activities an ordered array of the components of an emission or wave
spec.tra (spek''trı) i., fiz. tayf, spektrum
Electromagnetic radiation arranged in order of wavelength A rainbow is a natural spectrum of visible light from the Sun Spectra are often punctuated with emission or absorption lines, which can be examined to reveal the composition and motion of the radiating source
spec.tra (spek''trı) i., fiz. tayf, spektrum
A spectrum is a range of light waves or radio waves within particular frequencies. Vast amounts of energy, from X-rays right through the spectrum down to radio waves, are escaping into space. Arrangement according to wavelength (or frequency) of electromagnetic radiation. The visible, "rainbow" spectrum is the portion of the electromagnetic spectrum that is visible as light to the human eye. Some sources emit only certain wavelengths and produce an emission spectrum of bright lines with dark spaces between. Such line spectra are characteristic of the elements that emit the radiation. A band spectrum consists of groups of wavelengths so close together that the lines appear to form a continuous band. Atoms and molecules absorb certain wavelengths and so remove them from a complete spectrum; the resulting absorption spectrum contains dark lines or bands at these wavelengths
spec.tra (spek''trı) i., fiz. tayf, spektrum
a continuum of color formed when a beam of white light is dispersed (as by passage through a prism) so that its component wavelengths are arranged in order All forms of electromagnetic radiation can be dispersed to form a spectrum
spec.tra (spek''trı) i., fiz. tayf, spektrum
A curve showing amplitude and phase as a function of frequency or period, or how much of each type of shaking there is from an earthquake
spec.tra (spek''trı) i., fiz. tayf, spektrum
-A range of components, arranged in order For example, the spectrum of electromagnetic radiation is the array of wavelengths composing it
spec.tra (spek''trı) i., fiz. tayf, spektrum
Intensity or observed flux of electromagnetic radiation arranged as a function of wavelength A rainbow is an example of a spectrum of visible sunlight dispersed by the prismatic affect of raindrops The plural of spectrum is spectra
spec.tra (spek''trı) i., fiz. tayf, spektrum
distribution of electromagnetic radiation in order of wavelengths
spec.tra (spek''trı) i., fiz. tayf, spektrum
Display of component wavelengths (colours) of electromagnetic radiation
spec.tra (spek''trı) i., fiz. tayf, spektrum
The distribution of wavelengths and frequencies
spec.tra (spek''trı) i., fiz. tayf, spektrum
The distribution of power versus frequency in an electromagnetic wave Often used in the context of frequency allocations in reference to the frequencies allowed for a type of service out of the total available
