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

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

First wave feminism started in the late 19th century and carried on until the early 20th century the main focus of the movement was to give women more of a voice in the world and to end suffrage and give women the right to vote. It was first recognized as a movement at the Seneca Falls Convention in 1848 were people like Elizabeth Cady Stanton and Sojourner Truth had a massive impact in the movement.

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

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.

into three "waves" by different feminists in order to categories the different events that took place throughout the movement. The first wave mainly refers to the women’s suffrage (the right for women to vote) movements of the nineteenth and early twentieth centuries‚ which was mainly concerned with women’s right to vote. The second wave refers to the ideas and the behaviors‚ which are correlated with the women’s liberation movement‚ which began in the beginning of the 1960s. The third wave refers to

But‚ soon it grew. The teacher who started The Wave gained power very quickly and even had a bodyguard. The students were all the same‚ many didn’t take the time to think for themselves. Soon‚ The Wave grew to the whole school. There were two groups‚ The Wave members and non-Wave members. Members would use The Wave as an excuse to bully and get in fights with non-member people.

There are a lot of definitions of culture‚ we can name some: “That complex whole which includes knowledge‚ belief‚ arts‚ morals‚ law‚ custom‚ and any other capabilities and habits acquired by man as a member of society.” (Edward Tyler -1871). It could say too that culture involves two main human activities‚ what people think and what people do. Also culture is a symbolic of communication and style of this communication‚ which is socially transmitted or socially learning‚ so‚ it became in a
