Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

### Problem Description

Two loudspeakers in a plane, 6.0 m apart, are playing the same frequency. If you stand 11.0 m in front of the plane of the speakers, centered between them, you hear a sound of maximum intensity. As you walk parallel to the plane of the speakers, staying 11.0 m in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers.

Two small speakers, 0.680 m apart, are facing in the same direction. They are driven by one 666 Hz oscillator and therefore emit identical sound waves in phase with one another at the respective points of origin. (The speed of sound waves in air is 343 m/s.) Two speakers are side by side, with one speaker on the left and one on the right. The speakers are separated by a distance d and emit sound waves in the same direction. A man stands directly in front of the speaker on the right but a distance x away from the right speaker. (a) A listener wishes to stand in front of one of the speakers, at the closest point (i.e., smallest x-value) where intensity is at a relative maximum. At what distance x from the nearest speaker should she position herself? (Enter your answer in m.) m (b) The listener now wishes to stand at the closest point along that line where intensity is at a relative minimum. At what distance x should she position herself now? (Enter your answer in m.) m
Two audio speakers are placed on a vertical rail. Speaker A is placed at head-level while Speaker B is place at some variable height, Ay, above Speaker A. Both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.467 meters. Calculate the lowest height that Speaker B can be placed above Speaker A to produce a minimum of sound heard by person standing Ax = 6.03 meters directly in front of Speaker A. Image size: s ML Max ay AX
Two speakers sit 4.0m apart. Each is playing the same pure tone, of a single frequency sinusoidal sound wave. For simplicity, we can place these on the y-axis at y = +2.0m and at y = -2.0m. You stand on the centerline between the speakers, and 10.0m in front of them (this would be at y = 0m, x = 10.0m) At this location, you hear maximum intensity sound, a.k.a. constructive interference. You then walk in the +y direction until you hear a minimum intensity of sound, a.k.a. destructive interference. This happens when you reach y = 2.5m. (Your coordinates would now be x = 10.0, y = 2.5.) Interference is based on path length differences form different sources to the same detection point. Identify the paths from the two different speakers to the first observation point (10,0). How long is each of these paths?

In each of the four scenarios shown in the images, a large bat lets out a short burst of ultrasonic sound, which a smaller bat hears a moment later. If the large bat flies at 2.320 m/s and the small bat flies at 13.80 m/s, order the frequencies that the smaller bat detects in the four scenarios from highest to lowest. Assume that the speed of sound is 343.0 m/s. Highest frequency A D B. A B C Lowest frequency Answer Bank In Scenario C, part of the large bat's signal reflects off the small bat and returns to the large bat, warning it of the smaller bat's presence. If the initial signal has a frequency of 66.70 kHz, what return frequency fr will the large bat detect? Calculate the final frequency to four significant figures. fr Incorrect kHz Ꭰ
Two loudspeakers, 1.7 m apart, emit sound waves with the same frequency along the positive x-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? Assume room temperature of 20∘C.
An intensity detector can be moved along a straight track. a source of spherical waves is placed at one end of the track. When the detector is 2 m away from the source, it measures an intensity of 80 W/m2. What distance do we need to move the detector from that position to get a measurement 13 dB lower? Answer: 6.95m

A row of seats is parallel to a stage at a distance of 8.4 m from it. At the center and front of the stage is a diffraction horn loudspeaker. This speaker sends out its sound through an opening that is like a small doorway with a width D of 0.074 m. The speaker is playing a tone that has a frequency of 2.00 104 Hz. The speed of sound is 343 m/s. What is the distance between two seats, located near the center of the row, at which the tone cannot be heard?
An audio system is emitting a sound at a frequency of 676 Hz through two speakers separated by a distance d = 0.620 m. What's the shortest distance for a person to hear maximum intensity if he was facing the speaker on the right (see picture).
Two speakers are a distance d = 19.95m apart and emitting in-phase sound of frequency f = 55Hz. The sound is traveling at a speed of v= 339.8m/s.
