Waves, Sound, and Physical Optics
Two waves meet at a point. Wave A has a displacement of +0.4 m, and Wave B has a displacement of -0.6 m. What is the resulting displacement at that point?
Under what conditions does constructive interference occur?
Two waves with amplitudes of 0.7 m and 0.9 m interfere. If the phase difference between them is such that destructive interference occurs, resulting in a minimum amplitude of 0.2 m, what is the phase difference between the two waves?
A piano tuner is trying to tune a string to 440 Hz. When the tuner plays a 440 Hz tone along with the piano string, they hear 2 beats per second. What adjustments should the tuner make to the piano string to tune it correctly?
Two waves are traveling in the same medium. Wave A has an amplitude of 0.6 m and is in phase with Wave B, which has an amplitude of 0.8 m. What type of interference will occur, and what will be the resulting amplitude?
Two tuning forks are struck simultaneously. One has a frequency of 440 Hz, and the other has a frequency of 443 Hz. What is the beat frequency that will be heard?
Two sound waves produce a beat frequency of 4 Hz. If one of the original frequencies is 256 Hz, what is the other possible frequency?

Two wave pulses are traveling towards each other on a string. What happens when they meet?
Two waves are graphically represented. Wave 1 has a positive peak, and Wave 2 has a negative peak of the same magnitude at the same location. Sketch the resulting wave after superposition.
A wave with a displacement of +0.3 m meets another wave with a displacement of +0.5 m at the same point. According to the principle of superposition, what is the resulting displacement at that point?
