Electromagnetic radiation is, classically speaking, a wave of electricand magnetic fields propagating at the speed of light c through empty space. In this wave the electric and magnetic fields change their magnitude and direction each second. This rate of change is the frequency ν measured in cycles per second—namely, in hertz. The electric and magnetic fields are always perpendicular to each other and at right angles to the direction of propagation, as shown in Figure 2. There is as much energy carried by the electric component of the wave as by the magnetic component, and the energy is proportional to the square of the field
There is a greater magnetic field magnitude if field lines are close together. Magnetic field also exerts magnetic force which is given by the equation: F=IlBsinθ where F is the magnetic force, I is the current, B is the magnetic field and θ is the angle between I and B. From the equation, magnetic force is directly proportional to current, length of current loop, magnetic field and angle which were all proven in the experiment. In order to convert magnetic force in gram to Newton, the formula g *(1kg/1000g)* 9.8m/s2 (where g is the final reading in digital balance) should be used. By performing this experiment, I was able to visualize how magnetic field looks like and what factors may affect or change magnetic force.
Wave Energy Wave energy is a great alternative energy to fossil fuels. When people think of waves, they usually think of surfing, the beach, waves crashing down on the shore, but most people don’t think of energy being converted through waves. This energy is very unique, and more people should know about it, and should definitely be used more. Ocean wave energy is a good alternative to fossil fuels, because is renewable, a powerful clean source, and there are multiple options of ways to harness it. How It Works Wave energy converts the motion of waves into energy.
Bear in mind at all times that nothing travels faster than the speed of light – and for the mathematically minded – also bear in mind Einstein’s famous equation E = mc sq (E is energy, m is mass and c is the speed of light.) Because of the equivalence of energy and mass, the energy which an object has due to its motion will add to its mass. In other words, it will make it harder to increase its speed. This effect is only really significant for objects moving at speeds close to the speed of light. For example, at 10 per cent of the speed of light an object’s mass is only 0,5 percent more than normal, while at 90 percent of the speed of light it would be more than twice its normal mass.
3 shows the wave number of the Helmholtz equation (i.e. ) and the modified complex Helmholtz equation (i.e. ) in comparison with each other, clearly. Fig. 3(a) shows that the real part of wave number in the modified complex Helmholtz equation is much less than the wave number of the Helmholtz equation.
Thus, the relationship between an electric field and a magnetic field causes an electromagnetic wave. It can be said that the electromagnetic wave is the wave blend between electric fields with magnetic fields caused by electrical charges move accelerated. The finite-difference time-domain (FDTD) is a computational
If “Gravitation Concept” can be established, then the “pressurewarp” cause of gravitation will finally be understood. However, we are not done yet. Near Side Effect At least one detail that has been temporarily oversimplified should now be addressed. To complete this narrative, it is necessary for the warpon’s effect between the massive objects to be considered as judiciously as that on the outside. We have seen how the warp of one massive object can simulate the like-directed warp of another object creating simulated afterwarp.
3 Technical background 3.1 Solar energy Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is refined through Earth 's atmosphere, and is obvious as daylight when the Sun is above the horizon. When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When it is blocked by the clouds or reflects off other objects, it is experienced as diffused light. Solar irradiance is the power per unit area produced by the Sun in the form of electromagnetic radiation.
The bigger the values of the resistors, the bigger the values of the electromotive force will be resulted. This shows that the voltage range and resistor value is linear to each other, while perpendicular with the value of the current. For more clear details, see the date table above Conclusion Overall, both parts of this lab demonstrated the relationship outlined by Ohm’s Law and fostered a higher comprehension of the mechanisms driving circuit behavior. The direct relationships between voltage, current, and resistance allow measurement of the voltage and current without resistance being known. Moreover, the experiment also demonstrated how the different configurations of resistors, parallel or in a series could play a role in the behavior of the circuit and its components.
After calculating F + V − E, each is 2. To prove any convex polyhedrons will get = 2, take a cube and add a edge from one corner to the opposite. After adding the edge, the number of faces is 7, number of vertices is 8 and number of edges is 13. As adding an edge does not make the solid intersect itself, should equal to 2. So, F + V − E = 7 + 8 − 13 and the answer would be 2 which is the expected outcome.
