What are the characteristics of the spectrum of the cosmic background radiation?
The measurements at a number of discrete frequencies of the background radiation that fills space place their relative amplitudes reasonably close to the curve that characterizes the radiation of a blackbody with a temperature of 2.725 degrees absolute. As such, the peak amplitude is found at the frequency of about 162.5 GHz.
A quantum is a unit of?
A quantum in physics is a unit of measurement. It is the smallest discrete quantity of some physical property that a system or object can possess. It can, for example, be a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents, or it may refer to momentum or electric charge or any other physical quantity of a substance.
Why is radiation with shortest wavelength the most powerful?
In our Universe, EM radiation can only come in discrete chunks called "photons." The energy of each individual photon depends on the frequency of the EM radiation. Frequency depends on wavelength (or vice-versa): the shorter the wavelength, the higher the frequency. Thus, short wavelength photons have more energy. That's just how our Universe operates, whether or not we like it.
What is a polymorphic character?
" many bodies " traits. The three alleles for blood type is an example of this. Height/size is another example of this and many other variations in animal physiology are examples of this. Discrete traits, everybody has a heart, are in contrast to this, but even in discrete traits there are variations.
What is a simple definition of Einstein's quantum theory of light?
Light comes in discrete packets called photons. Each photon has energy E = h*frequency. h is called Planck's constant and is ~6.626e-34 Js
Why is the frequency spectrum of a discrete signal repetitions of the spectrum of the analog signal?
The analog signal is converted to discrete signal. Even after the conversion, the frequency of the actual signal still remains the same. If the frequency of the discrete signal is different from the analog signal, the reconstructed signal would be different again. This is not what we expect. So base spectrum for similar signals have same frequencies, whether they are discrete or analog. Why do the repetitions occur? The original analog signal is multiplied with a dirac pattern. The base frequency is then shifted to the places, where diracs are available. So long the diracs keep repeating, the base frequency do repeats. Hope you are convinced with my answer
Is frequency discrete in nature?
No, it is not.
What is the difference between stated and real class limits?
Real Class Limits are the class intervals of a frequency distribution when stated as in continuous categories. ie. 18.5-19.5, 20.7-34.7 Stated Class Limits are the class intervals of a frequency distribution when stated as discrete categories. ie. 19-21, 23-25
Is the frequency of a musical note played on a violin analog or discrete?
discrete
What is the difference between a frequency histogram and a relative frequency histogram?
Both divide the data into discrete groups or intervals. The frequency histogram gives the number of times the data occur in the particular group or interval, while the relative frequency histogram gives the fraction of times the data occur in the particular group or interval.
What are the kinds of cumulative frequency?
The two main kinds are discrete and continuous.
What is a discrete particle of energy?
A small discrete unit of energy is called a quantum of energy. The definition of quantum is a discrete quantity of energy proportional in magnitude to the frequency of the radiation that it represents.
Is the frequency domain plot of an alarm system discreet or contineous?
discrete because the signal of an alarm is periodic.
What does a baby of a mosquito a eat?
Discrete fourier coefficients are the samples of fourier transform of the non-pdc waveform, at pdc intervals

Is discrete signal continuous?
To answer this properly more context is needed but frequency is in most contexts continuous.
Is the frequency domain plot of a voice signal discrete or continuous?
The frequency domain of a voice signal is normally continuous because voice is a nonperiodic signal.
