Two Point Source Interference

• Antinodes - Path Difference = n𝜆
• Nodes - Path Difference = (n + 1/2)𝜆

Two Point Source Interference

n𝜆 = dsin(𝛳)

n: Antinodal Fringe Number

𝜆: Wavelength (m)

d: Slit-Spacing (m)

𝛳: Angle between Fringe on screen from the central position line

Iff 𝛳 is very small, then

n𝜆 = dx/L

x: Distance from Fringe on screen to central position (m)

L: Distance from slits to screen along the central position line (m)
