Exam 17: The Principle of Linear Superposition and Interference Phenomena

A string with a length of 3.0 m has two adjacent resonances at frequencies 112 Hz and 140 Hz. -What is the wavelength of the first harmonic?

The figures show standing waves of sound in six organ pipes of the same length.Each pipe has one end open and the other end closed.Note: some of the figures show situations that are not possible. -Which one of the pipes is resonating in its third harmonic?

Which one of the following will result in standing waves?

What is the distance to the nearest antinode from the fixed end of a guitar string vibrating at its first harmonic?

A 6.00-m long string sustains a three-loop standing wave pattern as shown.The wave speed is 2.00 × 10² m/s. -What is the frequency of vibration?

Which one of the following statements is true concerning the points on a string that sustain a standing wave pattern?

Vibrations with frequency 6.00 × 10² Hz are established on a 1.33-m length of string that is clamped at both ends.The speed of waves on the string is 4.00 × 10² m/s. -How many antinodes are observed for the resulting standing wave pattern?

Which one of the following superpositions will result in beats?

Two loudspeakers are located 3.0 m apart on the stage of an auditorium. A listener at point P is seated 19.0 m from one speaker and 15.0 m from the other. A signal generator drives the speakers in phase with the same amplitude and frequency. The wave amplitude at P due to each speaker alone is A. The frequency is then varied between 30 Hz and 400 Hz. The speed of sound is 343 m/s. -Determine the value of the maximum amplitude in terms of A.

The figures show standing waves of sound in six organ pipes of the same length.Each pipe has one end open and the other end closed.Note: some of the figures show situations that are not possible. -Which one of the pipes emits sound with the highest frequency?

The figures show standing waves of sound in six organ pipes of the same length.Each pipe has one end open and the other end closed.Note: some of the figures show situations that are not possible. -Which one of the pipes emits sound with the lowest frequency?
