What is Young's double-slit experiment ?

Young’s double-slit experiment uses two coherent sources of light placed at a small distance apart, usually, only a few orders of magnitude greater than the wavelength of light is used. Young’s double-slit experiment helped in understanding the wave theory of light. A screen or photodetector is placed at a large distance ’D’ away from the slits .

Why path difference is created between two coherent sources? How path difference is calculated?

The wave reaching light source from the second coherent source must travel a longer path than the wave reaching light source from the first coherent source. It is calculated by formula Δp = dsinθ where d is the distance between two coherent sources and sinθ is the angle from the center of the slits to the light source or photodetector.

How to Calculate Path difference in Young's double-slit experiment?

Path difference in Young's double-slit experiment calculator uses Path Difference=Distance between two coherent sources*sin(Theta) to calculate the Path Difference, Path difference in Young's double-slit experiment is because the wave reaching light source from the second coherent source must travel a longer path than the wave reaching light source from the first coherent source. Path Difference and is denoted by k symbol.

FAQ

What is Path difference in Young's double-slit experiment?

Path difference in Young's double-slit experiment is because the wave reaching light source from the second coherent source must travel a longer path than the wave reaching light source from the first coherent source and is represented as k=d*sin(ϑ) or Path Difference=Distance between two coherent sources*sin(Theta). Theta is an angle that can be defined as the figure formed by two rays meeting at a common endpoint and Distance between two coherent sources is the length at which both coherent sources are placed.Two sources that vibrate with a fixed phase difference between them are said to be coherent.

How to calculate Path difference in Young's double-slit experiment?

Path difference in Young's double-slit experiment is because the wave reaching light source from the second coherent source must travel a longer path than the wave reaching light source from the first coherent source is calculated using Path Difference=Distance between two coherent sources*sin(Theta). To calculate Path difference in Young's double-slit experiment, you need Theta (ϑ) and Distance between two coherent sources (d). With our tool, you need to enter the respective value for Theta and Distance between two coherent sources and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
