In a double slit experiment, when the distance between slits is increased 10 times, while their distance from the screen is halved, then the fringe width
- A becomes \(\left(\frac{1}{20}\right)\) times the original
- B becomes \(\left(\frac{1}{90}\right)\) times the original
- C remains the same
- D becomes \(\left(\frac{1}{10}\right)\) times the original
