Claudette is now working as assistant S2 Physics teacher and doubles as a Physics laboratory attendant. She was directly told that she was successful and she was given the job. With a smile, she started by saying that since sound waves have the same properties as for light these laws therefore do not change.Īs she was attempting to state them, the interviewer stopped her and congratulated her upon her confidence and bravery she showed in the room. Looking at Claudette’s face, the interviewer asked her to discuss the laws governing reflection and refraction of sound waves. What surprised the interviewer was Claudette’s ability to relate sound waves to other kinds of waves stating that these waves behaves the same way when they pass from one medium to another. Claudette started discussing these different media.

However, in the second step, she was required to discuss different media in which sound waves can propagate. This was enough to make Claudette pass the first level of the interview. Confidently, she responded that the properties are reflection, refraction, diffraction and interference. She was asked to state the properties of sound waves. On an interview for Physics placement in a certain school in Rwanda, Claudette a S.6 leaver who had applied for the job was asked about sound waves during the interview. Read the scenario below and answer the questions that follow. None of the above is the same in the air as it is on the string.ġ.1 CHARACTERISTICS AND PROPERTIES OF SOUND WAVES.The vibration on the string and the vibration in the air have the same wavelength.Which of the following statement is the right?

The sound is made by the vibration of the guitar string and propagates as a wave through the air and reaches your ear. What is the difference between a musical sound and noise?Ģ. Most people like to listen to music, but hardly anyone likes to listen to noise. What properties explain most the behavior of sound?ġ. Establish the fundamental frequency and 2nd harmonic, 3rd harmonic, in vibrating strings and in pipes.Give examples of musical pipe instruments.Explain beats and establish beat frequency.Establish relationship between characteristics of notes and sound waves.Carry out calculations relating decibels and intensity.Relate loudness and pitch to amplitude and frequency.Describe how sound propagates through a substance.By the end of the unit I should be able to analyze the effects of sound waves in elastic medium
