How would the angular separation of interferences fringes in young's double slit experiment change when the distance of separation between the slits and the screen is doubled?

Note that bandwidth = lamda D / d
and bandwidth = D @
Here @ is the angular separation.
So @ = lamda D / D d = lambda / d
So as D is not there in the expression the angular separation remains the same though the distance between slits and the screen is doubled.

What is meant by resolving power of the microscope?
The ability of a microscope to measure by separation images that would be difficult to see with the naked eye. This separation is called angular separation.
What is the difference between angular distance and angular displacement?
Here's the easiest answer: They have different names.....
Does angular speed depend on distance?
when something moves with constant angular speed (w), as in a rotating disk, the speed (v) as you move away from the center depends on distance (r), but the angular speed does not. Mathematically, v = wr.
What statements does not use the term angular size or angular distance correctly?
"The following" means the list after the question. There is no list following this question.
How a body can have angular momentum when it is moving in straight line?
If a body is moving in a straight line then it would have angular momentum about any point which is not along its line of motion. The magnitude of the angular momentum would be its velocity times the perpendicular distance between the line of motion and the point.
What is the angular separation between Polaris and Arcturus?
The declination of the star Arcturus is 19 degrees, 11 minutes, while Polaris has a declination of 89 degrees 15 minutes. Their angular separation is the distance between them, approximately 71 degrees.
How many arc seconds away is Vega?
An arc second is a measure of angular separation, not of distance. It is therefore an inappropriate unit for measuring the distance to a star.
Which scale on a protractor is used for determining distance in degrees?
Degrees are a measure of angular separation, not distances. You cannot, therefore, use the protractor for determining distances.
What quantity minute?
60 seconds, if measuring time or angular separation.
What evidence do you have that the moon is moving away from earth?
Laser distance ranging over the past 35 years.
What is meant by resolving power of the microscope?
The ability of a microscope to measure by separation images that would be difficult to see with the naked eye. This separation is called angular separation.
How do you model angular separation?
by doing x to the power of the sqrt of the log of 72
Angular distance in astronomy?
Azimuth.
What is the formula for angular distance?
g
What does latitude measure on the equator?
Latitude is the angular distance north or south of the equator. Longitude is the angular distance east or west of the equator.
What is the difference between angular distance and angular displacement?
Here's the easiest answer: They have different names.....
What is distance of the begin of the Orion's belt and the end of it?
The stars at the two ends, Alnitak and Mintaka are at a distance of 387 and 380 parces (1262 and 1239 lightyears) respectively. Due to the relatively small angular separation, the distance between the stars is approx 7 parsecs = 23 lightyears.
