Explanation:
It is given that,
Distance between the slits, d = 5 mm = 0.005 m
Distance between slit and screen, D = 1.4 m
For m = 2, and
For m = 2, and
Separation between two fringes is :
Hence, this is the required solution.
The answer is A
Hope that helps!
Before coming into conclusion first we have to understand both scalar and vector .
A scalar quantity is a physical quantity which has only magnitude for it's complete specification.
A vector quantity is that physical quantity which not only requires magnitude but also possesses direction for it's complete specification.
So the most important factor that differentiate vector from scalar is the direction.
As per the question the student is doing an experiment where he is recording the data obtained during the process.
In order to arrange them in data table, he should ask about the direction of the quantity under consideration.
Hence the correct option is the third option(C)i.e does the measurement include direction?
The velocity of sound in air is 358m/s
<h3>Calculations and Parameters</h3>
Given;
- Frequency= 256 Hz
- Water level= 30cm
- Position of resonance= 100cm
- The velocity of sound in air= ?
v= 2f(L2-L1)
= 2.2.56.(1- 0.3)
=358 m/s
