To solve this problem we will apply the concepts related to destructive interference from double-slit experiments. For this purpose we will define the path difference as,
Here,
= Wavelength
= Angle when occurs the interference point of destructive interference
Our values are given as,
Using the previous expression we have,
Therefore the distance between the two openings is
Answer:
The given statement is false.
Explanation:
For any negative vector
The magnitude of the vector is given by
As we know that square root of any quantity cannot be negative thus we conclude that the right hand term in the above expression cannot be negative hence we conclude that magnitude of any vector cannot be negative.
