Understanding Standing Wave Patterns at 50Hz Frequency

In summary, the conversation discusses the determination of the resulting wave in a standing wave when the fundamental frequency is 25Hz and the current frequency being fed to the string is 50Hz. The question is whether the 50Hz frequency is the second harmonic of 25Hz. It is confirmed to be the second harmonic and the number of wavelengths for a second harmonic standing wave oscillation is discussed. The conversation also mentions the calculation of waves for fundamental frequencies that are not multiples of 50Hz.

In a standing wave, if the fundamental frequency is 25hz
but the frequency that is currently being fed to the string is 50hz how do i determine what the resulting wave will look like?

Which harmonic of 25Hz is 50Hz?
 
  • #3
Is it the second one?
 
  • #4
Yes. So if the first mode of the fundamental has a half wavelength oscillation in the standing wave, how many wavelengths will there be for a 2nd harmonic standing wave oscillation?
 
  • #5
What about for fundamental frequencies that aren't multiples of 50hz.
How do i calculate what waves would be created?

Edit:nevermind this post, too early in the morning for me.
 

1. What is a standing wave?

A standing wave is a type of wave that occurs when two waves with the same frequency and amplitude travel in opposite directions and interfere with each other. This results in a pattern of nodes (points of no movement) and antinodes (points of maximum movement) that appear to be standing still.

2. Why is the frequency of 50Hz important in standing wave patterns?

The frequency of 50Hz is important in standing wave patterns because it is the frequency of the electrical power supply used in many countries. This means that many electronic devices and appliances operate at this frequency, making it essential to understand standing wave patterns at 50Hz.

3. What causes standing wave patterns at 50Hz?

Standing wave patterns at 50Hz are caused by the interference of two waves with a frequency of 50Hz. This can occur when an electrical signal travels through a medium, such as a wire, and reflects off of the end. When the original wave and the reflected wave meet, they create a standing wave pattern.

4. How do standing wave patterns at 50Hz affect electronic devices?

Standing wave patterns at 50Hz can affect electronic devices in a few ways. They can cause interference, leading to poor signal quality and malfunctioning of devices. They can also cause resonance, which can damage electronic components. Therefore, it is important for scientists to understand these patterns to prevent potential issues with electronic devices.

5. How can scientists study and understand standing wave patterns at 50Hz?

Scientists can study and understand standing wave patterns at 50Hz through various methods, such as mathematical calculations, computer simulations, and laboratory experiments. By analyzing the properties of the waves and the medium they are traveling through, scientists can gain a better understanding of how standing wave patterns at 50Hz behave and how they can potentially impact electronic devices.
