Concept explainers
The full angular width of central diffraction peak.
Answer to Problem 17P
Explanation of Solution
Given:
Width of slit,
Order,
Wavelength,
Formula used:
It is known that
Where,
Calculation:
Rearrange the given formula,
So,
The path difference is an integer multiple of the wavelength in constructive interference.
Substitute the given values in formula,
It is known that width
Now, calculate the angular width of the central diffraction
Conclusion:
The required angle is
