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.
Solution
Answer: C) Same wavelengths and amplitudes but different phases.
For total destructive interference (that is the resultant amplitude is zero everywhere) the interfering individual waves must have same amplitude and wavelength and also they mast have a phase difference of 180° between them.
When two waves of different wavelengths or amplitides superpose total destructive interference cannot never happen.

Destructive interference occurs at a certain location when O O O O O two waves with a phase difference of exactly half a cycle meet at that location. two waves with same amplitude but different wavelength meet at that location. two waves with a phase difference of exactly zero meet at that location. two waves with a phase difference of exactly a quarter cycle meet at that location. two waves with same amplitude but different frequency meet at that location.
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).
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...
Select the statements that are TRUE regarding interference. Two waves must be coherent or they will not interfere with each other. Only transverse type waves like waves on a string or light waves can experience interference. Two waves must both have spherical wavefronts in order to interfere with each other. Interference is a phenomenon that occurs for both particles and waves. When two waves interfere, the amplitude of the resultant wave is a combination of the amplitudes of the individual...
A group of students must design an experiment to determine how
the amplitude of a resultant wave pulse changes when two individual
wave pulses combine so that destructive interference is observed.
Both wave pulses travel toward each other. How should the students
produce the individual wave pulses so that total destructive
interference occurs.

1. Please answer the following questions regarding coherent
lights:
A.
B.
C.
What makes two light sources coherent? the same frequency the same frequency, and maintaining a constant phase difference the same amplitude, and maintaining a constant phase difference the same frequency and amplitude Monochromatic coherent light shines through a pair of slits. If the wavelength of the light is decreased, which of the following statements is true of the resulting interference pattern? The distance between the maxima stays the...
When transverse positive and negative pulses that have the same symmetric shape and size but travel in opposite directions meet, is it necessary that there be a moment when the string or wire on which they move is flat? If so, how do the pulses "know" to continue moving on the string? Two people on each end of a long rope send off a wave pulse. If both wave pulses are on the same side of the rope, describe what...
