Explanation:
hope this helps!
The point of contact the path difference is zero but one of the interfering ray is reflected so the effective path difference becomes λ/2 thus the condition of minimum intensity is created in the center.
The value of V is 640 km/hr.
<h3>What is Average velocity?</h3>
Average velocity is the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
To calculate the value of V from the question, we use the formula below.
- V' = (V+U)/2............ Equation 1
Making V the subject of the equation
- V = 2V'-U.............. Equation 2
From the question,
⇒ Given:
- V' = 520 km/hr
- U = 400 km/hr
Substitute these values into equation 2
- V = (520×2)-400
- V = 640 km/hr
Hence, the value of V is 640 km/hr.
