Simple Harmonic Motion:. Then, when the model fails, the student can justify the use of conservation of energy principles to calculate the change in internal energy due to changes in internal structure because the object is actually a system.
BIG IDEA 6: Waves can transfer energy and momentum from one location to another without the permanent transfer of mass and serve as a mathematical model for the description of other phenomena. Examples should include musical instruments. AP Physics 1. Search this site. Semester 1 Review. AP Physics Exam Review. Perusall Reading Assignment Tool. Direct Measurement Video. Assuming that the two instruments use the same strings is equivalent to stating that the two instruments have strings of equal linear mass density.
This situation represents a standing wave, thus we can relate the following equation for the first harmonic:. Then we can use the following equation to relate wavelength and speed which is known to frequency:. A sound played from a speaker is heard at an intensity of W from a distance of 5m. When the distance from the speaker is doubled, what intensity sound will be heard? The correct answer is. A stopped pipe closed at both ends sounds a frequency of Hz at its fundamental frequency.
What is the length of the pipe? A stopped pipe can be modeled with the following equation:. Frequency of beats is determined by the absolute value of the difference between two different frequencies. Thus, the beats frequency is 2Hz. Note that beat frequency is always a positive number. An open pipe can be modeled by the following equation:.
A student at a concert notices that a balloon near the large speakers moving slightly towards, then away from the speaker during the low-frequency passages. Sound is a longitudinal, or compression wave. A region of slightly more compressed air is followed by a region of slightly less compressed air called a rarefaction.
When the compressed air is behind the balloon, it pushes it forward, and when it is in front of the balloon, it pushes it back. This only works if the frequency is low, because the waves are long enough so that the balloon can react to them. Use the following equation to find the velocity of the wave, using its fundamental frequency and the length:. If you've found an issue with this question, please let us know.

Possible Answers:. Correct answer:. Explanation : We know from the question that Frequency is the inverse of period: The velocity of a wave is its wavelength multiplied by its frequency:. Report an Error. Example Question 1 : Sound Waves. Explanation : Two waves will emit a beat with a fequency equal to the difference in frequency of the two waves.
Example Question 1 : Electricity And Waves. Possible Answers: The shorter length creates a lower speed of sound. The shorter length strings produce higher frequencies. The shorter length strings produce lower frequencies. The shorter length creates a higher speed of sound. Correct answer: The shorter length strings produce higher frequencies.
Explanation : The speed of sound in air is constant, assuming that the temperature of the air is constant. Example Question : Ap Physics 1.Lesson 1 - The Nature of a Wave.
