# Science 8 Electromagnetic Spectrum Worksheet

If you want to be a scientist, then you should know a little about the Science 8-Electromagnetic Spectrum Worksheet. This worksheet is available in most schools and colleges. The first step of this worksheet is to select one of the two sources from above. A person has to compute the voltage across the sensor and then calculate the distance the electromagnetic wave has traveled.

Then the person has to read the frequency of the waves are transmitted at. They have to compute this frequency and then calculate the average power of that signal and compare it with the usual low-power signals.

You will notice that the average power is quite a bit lower than the normal human hearing. You may also find that the energy transmitted from the source is very close to that of the normal radio frequency waves. The person has to read the frequency reading twice.

When reading the frequency for normal radio frequencies, there is no need to compute the voltages between each band. But, if you compute the voltages between the different bands, you will find that they do not add up to more than about 2.6 volts. You will be able to understand why people say that there is very little difference between radio frequency and microwave waves.

When the person is attempting to calculate the voltage across the sensor, it may take them several attempts to get a single frequency reading. If you use the same voltages in more than one frequency reading, then you will be able to compute a single number for the voltage across the sensor, but you will also see that the differences between the readings are very small.

Then, you will be able to use the frequency reading that you computed and calculate the VSWR. You will also learn about the DC resistance.
