  The weird music of Sarah and Ali - $5 Physics quiz

  
  

   

  
  

  

  
  

  Along with her musical team band, Sarah wants to become a famous and worldwide selling artist. She is incredibly passionate about musical instruments, particularly in the acoustic guitar. Aside from her interest in music, she also loves to dig down into theories about the world of physics.

  
  

  

  
  

  One day, a team member named Ali proposed a suggestion for trying to synchronously play the acoustic guitar along with Sarah because he feels that it is much more soothing to hear multiple instruments playing at the same time. Sarah loved Ali's suggestion and as soon as they played the guitar together, suddenly a loud thump of noise popped up. Both Sarah and Ali were confused about why that sudden loud noise got produced as they both played the guitars simultaneously.

  
  

  Now, using the concepts of Physics, answer the following: 

  
  

  Why was there a moment of loud thumping noise while Sarah and Ali attempted to synchronously play the acoustic guitar?

  
  

  Please try to write your answer in 185 words or less in the comments section below. Please submit your answer by July 15th midnight, Bangladesh time.

  Tanveer Tausif Ratul (Winner, $5)

  
  

  Tanveer's answer was written in clear language that resonated well with the audience. The way he described the concepts was easy to understand for anyone. Though his answer had some statements, which may not be scientifically correct (example, definition of phase needs to be corrected), it does not hurt the understanding. 

  
  

   

  
  

  The runner-up of this quiz is: 

  
  

  

  
  

  Zarin Sadaf Snigdha (Runner-up, $3)

  
  

  Zarin's response was scientifically correct. But the description was more technical and may not be clear to common audience. But still one of the best answers.
