Question
Consider the double slit experiment for light. Complete each statement as it would apply to Young's experiment (for each statement select "Increases", "Decreases", or "Cannot be Predicted"). If a variable is not mentioned, consider it to remain unchanged.
The options are Increases, decreases or nannot be predicted.
If the distance to the screen increases, fringe separation ...?...
If slit separation decreases and the distance to the screen decreases, fringe separation ...?...
If the wavelength of the light used increases, fringe separation ...?...
If slit separation increases, fringe separation ...?...
For the fringe separation to remain unchanged, wavelength ..?.. while the distance to the screen decreases.
If the distance to the screen triples and slit separation doubles, fringe separation ...?...
If the frequency of the light used decreases, fringe separation ...?...
Explanation / Answer
1) increases
2) nannot be predicted
3) increases
4) decreases
5) increases
6) increases
7) increases (since lamda = c/f)
we know, fringe width = lamda*R/d
here
lamda is wavelngth of the light
R is the distance between the slits and screen
d is the slit separation.
