Answer:

Period of the signal.

Explanation:

So, this question is all about a concept in physics or astronomy which is called or known as Radiation Astronomy and Galactic Nuclei that are active. This concept talks most about Quasars; a powerful radiating object which derives its power from black holes.

When You take a look at Quasars, we get the to know that the more you think you can see, the more they move away from us.

Thus, when "You are observing the radiation from a distant active galaxy and you notice that the amplitude of the signal varies in strength regularly over a certain period. The maximum possible size for the source of this radiation can now be calculated from the "PERIOD OF THE SIGNAL.

NB: not the amplitude but the period.

Which of electromagnetic radiation has the shortest wavelength?
9966 [12]

Answer:

The electromagnetic radiation with the shortest wavelength are gamma rays.

Explanation:

Photons are the particles that constitute light and its kwnow that lights propagates as electromagnetic waves.

The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, which are transverse waves formed by an electric field and a magnetic field perpendicular to it.

The distribution of the radiation in the electromagnetic spectrum can also be given in wavelengths, but it is more frequent to work with it at frequencies, the highest being that of gamma rays, followed by X-rays, ultraviolet rays and the visible region , and those of lower frequencies, which correspond to infrared, microwave and radio waves.        

The energy given for each wavelength can be found by means of the following equation.

E = h\nu  (1)

but c = \lambda \cdot \nu

\nu = \frac{c}{\lambda}

E = \frac{hc}{\lambda}   (2)

Where E is the energy, h is the planck's constant and \lambda is the wavelength.

                   

So, it can be see in equation 2 that when the wavelength increases the energy decreases (inversely proportional).

Hence, the electromagnetic radiation with the shortest wavelength are gamma rays.

What is the reason behind superposition?why waves behave this way?
marshall27 [118]

Explanation:

Most waves appear complex because they result from two or more simple waves that combine as they come together at the same place at the same time—a phenomenon called superposition. Waves superimpose by adding their disturbances; each disturbance corresponds to a force, and all the forces add
