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:
if you like my answer markme barinlest:)
Explanation:
An acid is a substance or compound that releases hydrogen ions (H+) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H+), and chloride ions (Cl-) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding.
Answer:
a) 4.6*10^{-5} J
b) 6133.33 J/C
c) 94358.9 C
Explanation:
(a) We have that the change in the kinetic energy equals the net work over the charge. Hence we have
where Ek is the kinetic energy, W is the work of the external force and WE is the work done by the electric field. By replacing we obtain:
(b) The potential difference is computed by using:
(c) With the work done by the electric force we can calculate the Electric field. By using the following formula we obtain:
where we have used d=6.5cm=6.5*10^-9m and q=7.5nC=7.5*10^-9C
hope this helps!!
The radiation detector that uses detection of flashes of light is a <u>scintillation counter.</u>
<h3>What is a scintillation counter?</h3>
A scintillation counter detects and measures ionizing radiation by using the excitation action of incoming radiation on a scintillating substance and detecting the light pulses that arise.
One of the most critical considerations for anyone who operate with or near radiation is being aware of the amounts of radiation present.
This is generally performed through the use of several types of radiation detectors.
The radiation detector that uses detection of flashes of light is a scintillation counter.
Hence,scintillation counter is the correct answer.
