What effect does the distance between the slit and the screen have on the interference pattern?

More interference occurs when d is wider. The spacings between different fringes decreases as the distance between the slits increases because it is dependent on L. Increasing the wavelength of the light increases the spacing between different fringes since the spacing between different fringes is wavelength dependent.

What happens when you decrease the distance between slits?

With a single slit the spacing increases with wavelength, though if you reduce the width of the slit enough, the number of fringes decreases and their size increases.

What happens to the distance between the spots when the diffraction grating is moved closer to the screen?

Yes. If we move the screen farther from the double slit, the screen will intercept the light from the grating after the bright lines in the pattern have been able to spread out farther, increasing the distance between the bright spots on the screen.

What is the effect on the interference fringes in a Young’s double slit experiment when I the separation between the two slits is decreased?

With the decrease in separation between two slits, ‘d’ the fringe width increases. Where, s = size of the source, S = distance of the source from the plane of two slits. As the source slit width increase, fringe pattern gets less and less sharp.

How does a single slit diffraction pattern differ from a double slit interference pattern?

In a single slit diffraction, light spreads out in a line perpendicular to the slit. But in a double slit diffraction, light diffracts when passing though the slits, but the light from those then interferes to produce an interference pattern on the screen.

How did the distance between the maxima change when slit separation was increased?

In general, as the slit separation is increased, the distance between the maxima decreases. distance from the central maximum to the maximum (y) are inversely proportional.

How does distance affect diffraction?

For a given wavelength, the greater the distance between the slits, the smaller the angles at which the difference between the two paths is equal to a multiple of half wavelengths, the closer the intervals between maxima and minima on the screen, the less distinct the interference pattern.

What happens to the diffraction pattern when the distance between slits within?

When the distance between slits within the grating is increased, bands get closer together and eventually merge to form an image of the grating.

What is the effect on the interference fringes to a Young’s double slit experiment when the width of the source slit is increased?

As the source slit width increase, fringe pattern gets less and less sharp. When the source slit is so wide the above condition does not satisfied and the interference pattern disappears.

What is the relationship between screen distance and screen pattern?

The light wavelength, slit width, and (distance between slits for the double slit) determine the ANGLE for the screen pattern. Therefore, the screen pattern expands with screen distance. I assume you mean the pattern in something like the double-slit experiment. The angular separation of the fringes (measured from the slits) remains the same.

How does slit-screen distance affect the angular separation of fringes?

The angular separation of the fringes (measured from the slits) remains the same. However, the distance between the fringes seen on the screen increases as the slit-screen distance increases. That’s pretty obvious if you think about it.

What happens to fringes when the distance between slits is increased?

Thus, more brighter fringes are formed at the screen on increasing the width of the slits. (ii) : Coloured fringes are formed at the screen if monochromatic light is replaced by the white light. So, width of the fringes gets decreased if the distance between the slits (d) is increased and thus we get narrower fringes.

How does increasing the screen distance affect the spacing between fringes?

Thus increasing (decreasing) the screen distance L increases (decreases) the spacing between fringes, the pattern staying the same. I’m just a lay person who reads a lot.
