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:**

Work = F * s where s is the distance F moves

Since F is stationary, in this case, **"no work" **is done by either person

exit temperature of air is 776.128k

the mass flow rate of exhaust gases is 14.89kg/s
