If two sources emit waves with the same wavelength and a constant phase difference ϕ, they are said to be coherent.
<h3>What is coherent source ?</h3>
- If the frequency and waveform of two wave sources are the same, they are coherent. Waves' optimal quality of coherence makes stationary interference possible.
- When the phase difference between two beams of light is constant, they are coherent; if the phase difference is random or changes, they are noncoherent.
- The concept of a superpositioning at the core of quantum physics and quantum computing is referred to as "quantum coherence." Quantum coherence specifically considers a scenario in which a wave property of an item is split in two and the two waves coherently interfere with one another.
- The interference visibility, which examines the size of the interference fringes in relation to the input waves, is an easy way to measure the degree of coherence; correlation functions provide a precise mathematical definition of the degree of coherence.

Answer:
transition metals im sorry if this was too late
True. E=energy M=mass c= speed of light
Answer:
option D
Explanation:
given,
length of the pipe, L = 0.96 m
Speed of sound,v = 345 m/s
Resonating frequency when both the end is open
n is the Harmonic number
2nd overtone = 3rd harmonic
so, here n = 3
now,
f = 540 Hz
The common resonant frequency of the string and the pipe is closest to 540 Hz.
the correct answer is option D
