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.

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?
Answer the following step by step: A)The range of frequencies audible to humans is from about 20 Hz to 20kHz. Assuming that the speed of sound in air is 343 m/s, the wavelength of a 20 kHz sound is: a) 58 cm b) 1.8 cm c) 6860 km d) 400 km B) A 640 Hz tuning fork is placed on the open edge of a resonance tube of initial length L = 0 cm. Assume that the speed of sound is 330 m/s. As the tube becomes longer, successive whistles of maximum intensity (for example, from L1 to L3, or from L3 to L5, etc.) are heard at intervals L. What is the value L. Note: Be careful with the units a) 51.7 cm b) 194 cm c) 19.4 km d) 25.8 km e) 12.9 cm C) In a tube that has one end closed (the other open), with a fundamental frequency of 256 Hz, which of the following frequencies cannot produce resonance? a) 5.12 kHz b)There is no restriction to any frequency c) 19.7 kHz d) 768 Hz e) 1.28 kHz
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 0.759 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 = 4.50 meters directly in front of Speaker A. sy AX Image size: S M L Max

A person is sitting at an angle a off to the side of a diffraction horn that has a width D of 0.068 m. This individual does not hear a sound wave that has a frequency of 8400 Hz.

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.

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.
