Given:
- Wavelength of light used in the first case, λ1 = 700 nm
- Number of fringes observed in a certain segment of the screen, n1 = 16
- Wavelength of light used in the second case, λ2 = 400 nm
- Number of fringes observed in the same segment of the screen in the second case, n2 = ?
To find:
The number of fringes observed in the same segment of the screen in the second case.
Concept:
In a Young's double-slit experiment, the number of fringes observed is given by the formula:
n = (2d/λ) * L
where:
- n is the number of fringes observed
- d is the distance between the slits
- λ is the wavelength of light used
- L is the distance between the double slits and the screen
Calculation:
Let's assume the distance between the double slits and the screen, L, is the same in both cases.
In the first case, n1 = 16
In the second case, n2 = ?
We can equate the two formulas to find the relationship between n1 and n2:
(2d/λ1) * L = (2d/λ2) * L
Cancelling out L and d from both sides of the equation:
2/λ1 = 2/λ2
Substituting the given values:
2/700 = 2/400
Simplifying the equation:
1/700 = 1/400
Cross-multiplying:
400 = 700
Since the equation is not satisfied, it means that the number of fringes observed in the second case, n2, will be different from n1.
Therefore, option D) 28 is the correct answer.
