Problem 1: Interference of Orange Light through a Double Slit
Introduction
This problem involves the phenomenon of Young’s double-slit interference pattern with orange light, requiring application of the principles of wave interference, specifically calculating fringe spacing and positions on a screen. We use the physical principles of constructive and destructive interference to solve each part.
Key Idea
The key physical principle involved is wave interference, where the fringe positions depend on the wavelength, slit separation, and distance to the screen. The equations governing the positions of bright and dark fringes are derived from the path difference condition for constructive (bright fringes) and destructive (dark fringes) interference.
Stock of Data
- Wavelength of orange light, λ = 620 nm = 620 x 10-9 m
- Slit separation, d = 0.580 mm = 0.580 x 10-3 m
- Distance to screen, L = 1.20 m
- Fringes to calculate:
(a) distance between second-order bright fringes,
(b) distance between the central maximum and the fourth dark fringe,
(c) distance between the third bright fringe on one side of the center and the third dark fringe on the other side.
I.D. Equation
The general formula for fringe position:
- For bright fringes: ym = (m λ L) / d
- For dark fringes: yn = ((n + 0.5) λ L) / d
where m and n are fringe order numbers.
Solve
Calculate each part step-by-step:
(a) Distance between the two second-order bright fringes:
Yes, this corresponds to the difference in positions of m=2 and m=1 bright fringes.
(b) Distance from central maximum to one of the fourth dark fringes:
n=4 dark fringe position, compare with central maximum (n=0).
(c) Distance between the third bright fringe on one side and third dark fringe on the other:
positions of m=3 bright and n=3 dark on opposite sides.
Substitute in Numerical Data
Calculate each quantity precisely:
(a) Second-order bright fringes:
y2 = (2 x 620 x 10-9 x 1.20) / (0.580 x 10-3) = (2 x 620 x 10-9 x 1.20) / 0.580 x 10-3
= (1.488 x 10-6) / (0.580 x 10-3) ≈ 2.565 mm
Similarly, y1 for the first bright fringe:
y1 ≈ 1.283 mm
Difference = y2 - y1 ≈ 1.282 mm
(b) Distance from center to the 4th dark fringe:
y4 = (4 + 0.5) x 620 x 10-9 x 1.20 / 0.580 x 10-3
= (4.5 x 620 x 10-9 x 1.20) / 0.580 x 10-3
= 4.182 mm
The distance from central maximum to the 4th dark fringe is approximately 4.182 mm.
(c) Distance between the 3rd bright fringe and 3rd dark fringe on opposite sides:
- Bright fringe position: y3 ≈ (3 x 620 x 10-9 x 1.20) / 0.580 x 10-3 ≈ 4.847 mm
- Dark fringe position (on opposite side): y3 for dark fringe:
y3 = (3 + 0.5) x 620 x 10-9 x 1.20 / 0.580 x 10-3 ≈ 8.115 mm
Difference:
|8.115 mm - 4.847 mm| ≈ 3.268 mm
Sanity Check
The calculated fringe spacings are in the millimeter range, consistent with typical optical interference patterns, confirming correctness.
Problem 2: Double-Slit Experiment with Two Colors
Introduction
This problem explores the interference fringes produced by two different wavelengths and the condition under which two fringe orders from different wavelengths coincide.
Key Idea
The key physical principle is interference, with the condition that fringes of different wavelengths align when their fringe positions are equal: mλ1 = nλ2. We seek the unknown wavelength λx and interpret what color it might correspond to.
Stock of Data
- Wavelength of red light, λred = 680 nm = 680 x 10-9 m
- Fringe order for the first wavelength: m=2 (second-order bright fringe)
- Fringe order for the second wavelength: n=3 (third-order bright fringe)
I.D. Equation
The condition for coincidence of fringes:
m λred = n λx
Solve
Rearranged:
λx = (m / n) λred
Substitute:
λx = (2 / 3) x 680 x 10-9 m = (0.6667) x 680 x 10-9 m ≈ 453.33 x 10-9 m
So, λx ≈ 453 nm.
Answer for (a):
The wavelength of the other color- Approximately 453 nm.
Color Correspondence (b):
A wavelength around 450 nm corresponds to blue or blue-violet light, depending on the spectral boundary definitions.
Sanity Check
The wavelength falls within the visible range and is consistent with blue/violet light known to have wavelengths near 450 nm, confirming the plausibility.
Conclusion
Both parts of the problem demonstrate how interference fringe coincidence can be used to determine unknown wavelengths and interpret spectral colors, illustrating the fundamental wave nature of light and the interference phenomenon.
