Answer:
0.35 m
Explanation:
Constructive interference occurs when the difference in the distance between the two speakers is
0, λ, 2λ,...
Here λ = v/f = 343/490 = 0.7m
The first point of interference is the initial point which would mean the distance is the trivial solution of 0 .
A microphone is placed half-way between the speakers and then moved along the line joining the two speakers until the first point of constructive interference is found.
Let x be the distance from the midpoint to the next interference.
This occurs when 1.5 + x -(1.5 - x) = 0.7
so 2x = 0.7 which means x = 0.7/2 = 0.35m

Long time ago, people saw the constellations as patterns in the sky. They names these patterns and tell stories about them. What people saw laong time ago are just mere patterns which forms animals and shapes. We got the names of our constellations from the Greeks who named the constellations after the mythological heroes and mythological legends.
For a single slit illuminated with a 500 nm light gives a diffraction pattern on a far screen,the angle is mathematically given as
theta=25.3
Option A is correct
<h3> What angle does the 18th minimum occur?</h3>
Generally, the equation for the the angle is mathematically given as
Therefore
In conclusion
theta/7=16/5
theta=10*7/5
theta=25.3
