we know that
the speed is equal to
The slope of the line on the graph is equal to the speed of the car
so
during the segment B the slope of the line is equal to zero
that means
the speed of the car is zero
therefore
<u>the answer is the option B</u>
The car has come to a stop and has zero velocity
Constructive interference happens when this condition is satisfied:
This means that the difference in the distance traveled by the waves, from the slit to the screen, is equal to the whole multiple of the wavelength.
If we say that the distance between two interference fringes is much smaller than the distance from the slit to the screen, we can use the following approximation:
Finally for the bright spots we have:
The spacing between bright spots is:
