Longitudinal design is defined as a special kind of systematic observation, implemented by correlational researchers, which involves the tasks of obtaining measures of variables of interest in multiple waves over time.
<u>Explanation:
</u>
Longitudinal design is one of the known systematic observation pattern followed by the correlational researchers in which a subject of experiment is observed for a significantly long span.
The three types of longitudinal design are: panel study, cohort study and retrospective study. The complete design involves the multiple set of observations over a variable or subject. Longitudinal design is often used in clinical psychology to study rapid fluctuations in the behaviour.

1. Stop transmitting start and stop sending photons. This is typical morse code like transmissions of information. By varying the pattern of starts stops you vary the information sent. Also used in digital communications over radios, modems, and pulse dialing over radio/phones.
<span>2. Change the frequency. You use a pattern of shorter and longer wavelengths of radio waves higher and lower energies of individual photons to transmit information. This is frequency modulation </span>
The electromagnetic radiation that will be smartest to use is gamma rays.

Electromagnetic radiation</h3>
These are waves that does not require material medium for their propagation.
The wave with high frequency has a greater rate of penetration while those with high wavelength has lesser rate of penetration.
Thus, it will be smart to use the wave with high frequency, which means a low wavelength. The electromagnetic radiation with the highest frequency and low wavelength is gamma rays.

Power = (voltage) x (current)
1 watt = (1 volt) x (1ampere)
= 1 "volt-amp" or 1 "amp-volt" .
