observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the maximum amplitude. Standing waves have different

In comparison to the initial civilizations discussed in chapter two‚ the second wave empires were much larger and significantly more powerful. However this is nothing special because through much of history‚ empires and political

differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in phase perpendicular to each other and to the direction of propagation. EMR exists in different wavelengths and frequencies ranging from gamma rays to radio waves which make up the EM spectrum. Plasma is categorized as the fourth state of matter because its character is more complex than solid‚ liquid

An imaginary line that joins all the points on the crest of a wave. The direction of propagation of a wave is perpendicular to its wavefront. A transverse wave is a wave in which particles of the medium oscillate in the direction of the propagation of the waves. Water waves and electromagnetic

My preliminary diagnoses of the cause of the high death rate would be that the heat wave worsened the health of Chicagoans who were already diagnosed with serious health conditions. The author poses a question that the heat wave may have affected the individuals who were already stricken with a disease. These individuals include African Americans and

series of overtones or harmonics Younger people can usually hear pitches with frequencies from about 20 hertz (infrasonic) to 20‚000 (ultrasonic) hertz. We can’t hear above 20‚000 hertz or below 20 hertz (ultra and infrasonic waves). Light is both part particle and part wave. Light is "the electromagnetic radiation that may be perceived by the human eye". It consists of photons‚ which are massless bundles of concentrated electromagnetic energy.
