Given:
The distance between the two narrow slits is
The distance between the slit and the screen is
The wavelength of the light is
Required: Distance of the third bright fringe from the central maximum.
Explanation:
The third bright fringe will have m = 3.
The distance of the third bright fringe from the central maximum can be calculated by the formula
On substituting the values, the distance can be calculated as
Final Answer: The distance of the third bright fringe from the central maximum is 0.0179 m.
The product is sodium chloride. In its clean, pulverized form, that's common table salt.

The magnetic field at the center of the arc is 4 × 10^(-4) T.
To find the answer, we need to know about the magnetic field due to a circular arc.
<h3>What's the mathematical expression of magnetic field at the center of a circular arc?</h3>
- According to Biot savert's law, magnetic field at the center of a circular arc is
- B=(μ₀ I/4π)× (arc/radius²)
- As arc is given as angle × radius, so
B=( μ₀I/4π)×(angle/radius)
<h3>What will be the magnetic field at the center of a circular arc, if the arc has current 26.9 A, radius 0.6 cm and angle 0.9 radian?</h3>
B=(μ₀ I/4π)× (0.9/0.006)
= (10^(-7)× 26.9)× (0.9/0.006)
= 4 × 10^(-4) T
Thus, we can conclude that the magnitude of magnetic field at the center of the circular arc is 4 × 10^(-4) T.
