Two transverse pulses meet with total destructive interference. The pulses must have the A same wavelength and phase but different amplitudes. B same amplitude and phase but different wavelengths. C same wavelength and amplitudes but different phases. D same wavelength, amplitude and phase.
Destructive interference is when two pulses occupy the (different, positive, or same) location on a string or spring and are on the (initial, final, same, or opposite) of the equilibrium location (regular spring or string line). Constructive interference is when two pulses occupy the (different, positive, or same) location on a string or spring and are on the (initial, final, same, or opposite) of the equilibrium location (regular spring or string line).
Learning Goal:
To gain an understanding of constructive and destructive interference.
Consider two sinusoidal waves (1 and 2) of identical wavelength ?, period T, and maximum amplitude A. A snapshot of one of these waves taken at a certain time is displayed in the figure below. (Figure 1) Let y1(x,t) and y2(x,t) represent the displacement of each wave at position x at time t. If these waves were to be in the same location (x) at the same time, they...
Two beams of coherent light travel different paths, arriving at point P. If the maximum destructive interference is to occur at point P, what should be the path difference between the two waves? Two beams of coherent light travel different paths, arriving at point P. If the maximum destructive interference is to occur at point P, what should be the path difference between the two waves? The path difference between the two waves should be one and one-quarter of...

In a double-slit experiment, can you get destructive interference as the central fringe of the interference pattern? Why or why not? A. Yes, the path length can be different by exactly one wavelength. B. Yes, the path length can be different by exactly one-half wavelength. C. No, the path lengths from the two slits are always different. D. No, the path lengths from the two slits are always equal. E. Yes, the path length can be different by exactly two...
Two loudspeakers, labeled A and B, emnit sound waves in every direction. Both speakers emit sound with the same wavelength, and they are in phase (they emit peaks of the sound wave at the same time). The location labeled C is a location of constructive interference, and the location labeled D is a location of destructive interference. The distances from the loudspeakers to the locations are as indicated. (Picture may not be to scale!!) (a) What is the wavelength of...
In this problem wa wil consider the path differencs between two waves emitted by two source constractive interfenence to occur the net phase diference between that start out in phase. Recall that for rvo waves must be 0, 2r 4.., and for destructive interference to occur the net phase difference betweern two waves must be 3 5 ! Iwo source are in phase and emit waves that have a wavelength of 0.44 m. Determine whether constructive, occurs at a point...
To understand the cause of constructive and destructive interference for the double-slit experiment, and to explain how the interference pattern depends on the parameters of the emitted waves. For this tutorial, use the PhET simulation Wave Interference. This simulation allows you to send waves through a variety of barriers and look at the resulting interference patterns. Start the simulation. You will see three possible selections: Waves, Interference, and Slits. To change between simulations at any point, select the desired simulation...
8-Fully constructive interference between two sinusoidal waves of the same frequency occurs only if they: A. travel in opposite directions and are in phase B. travel in opposite directions and are 180o out of phase C. travel in the same direction and are in phase D. travel in the same direction and are 180° out of phase E. travel in the same direction and are 90o out of phased
