And it's a lot not, and finally just put it into the calculator and let it do all the hard work. Two, three significant digits. You get one thousand one hundred and fifty volts per meter, and then finally we are going to take the little I don't I don't know if you can call it a shortcut, but that using this simple relation for electric and magnetic fields, you see that you're be our mess is simply e armas divided by sea and using the value we just got Preferably not the rounded.

Often you let the calculator tell you that it is three point eight, two times ten to the minus six Tesla. In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true.

The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics. In mathematics, algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

Ask unlimited questions. The behavior of electromagnetic radiation clearly exhibits wave characteristics. But we shall find in later modules that at high frequencies, electromagnetic radiation also exhibits particle characteristics. These particle characteristics will be used to explain more of the properties of the electromagnetic spectrum and to introduce the formal study of modern physics. Another startling discovery of modern physics is that particles, such as electrons and protons, exhibit wave characteristics.

This simultaneous sharing of wave and particle properties for all submicroscopic entities is one of the great symmetries in nature.

Figure 1. Energy carried by a wave is proportional to its amplitude squared. With electromagnetic waves, larger E -fields and B -fields exert larger forces and can do more work. But there is energy in an electromagnetic wave, whether it is absorbed or not. Once created, the fields carry energy away from a source. If absorbed, the field strengths are diminished and anything left travels on. Clearly, the larger the strength of the electric and magnetic fields, the more work they can do and the greater the energy the electromagnetic wave carries.

This is true for waves on guitar strings, for water waves, and for sound waves, where amplitude is proportional to pressure. In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields. See Figure 1. Thus the energy carried and the intensity I of an electromagnetic wave is proportional to E 2 and B 2. In fact, for a continuous sinusoidal electromagnetic wave, the average intensity I ave is given by.

Algebraic manipulation produces the relationship.
