The Fundamentals of Radio Wave Propagation

How do radio waves get from one location to another? Why does a signal at generated at Point A, which is several thousand miles away, reach Point B without a complicated myriad of connecting wires? The answer, in three words, is radio wave propagation. Radio wave propagation theory is of particular importance to wireless

Radio waves travel at approximately the speed of light.  In free space, they also travel in straight lines, thus, in order for them to be transmitted from the origin to the destination, both the transmitter and the receiver must be in the other’s line of sight or the signal must arrive through some sort of reflected path.

  1. Investigating the speed of travelling waves in water.

    Theoretically, in the v2 vs. depth graph, all the points should lie on the line of best fit, but due to error, none of them lay on the line. Error bars can be drawn, to represent the possible values that the speed and depth could be.

  2. Deviation of Light by a Prism.

    (I - R1) + (E - R2) = ? (40 - 25.2) + (59.5 - 34.8) = ? 14.5 + 24.7 = 39.2� Therefore 39.2� is the angle of deviation for the incidence ray of 40�. Example Calculation 2 While using the above described method I also noticed another method to calculate the angle of deviation, which has less calculations, is shorter and is simpler to understand.

  1. An Investigation into the Effect on the Critical Angle by Changing the Colour of ...

    the blue light entered the median at a larger critical angle to achieve total internal reflection. The red light had a smaller critical angle because of its longer wavelength. A longer wavelength means that it can refract easier and reach the critical angle sooner.

  2. To investigate how the depth of the water will effect the speed of a ...

    There were no anomalies but the data is not one hundred percent exact it still shows clearly the relationship between the two. Conclusion: The results I recorded show with accuracy that my prediction was correct and that according to the equation It shows that the velocity of the wave increase as the depth of the water does.

  1. Properties of waves

    sound waves are an example of longitudinal waves that we encounter every day 2. sound waves traveling in air compress and expand the air in bands 3. as sound waves pass by molecules in the air move backward and forward parallel to the direction that the sound travels XIII.

  2. Is there any rule governing the angle light is refracted through?

    Same colour light, white light is made up of different waves, some travel slower than others. If you changed the colour of the light half way through the experiment the results would be very unreliable. E.g. at the start you used red light, but then switched to violet light during the experiment.

  1. Sideways Displacement of a Light Ray

    scratch, so I will not keep it near the edge of the table and I will make sure that it is in a safe position. * the ray box is connected to the plug, so I have to be careful with the electricity, also during the experiment the ray box

  2. Investigating the factors which affect the sideways displacement of a light ray through a ...

    Then I will extend the incident ray so that it continues through and out of the glass block. This is called the original ray. To find the sideways displacement I must measure using a mm ruler the length between the emerging ray and the original ray.
