Two slits are separated by a distance of `0.5mm` and illuminated with light of `lambda=6000Å`. If the screen is placed `2.5m` from the slits. The distance of the third bright image from the centre will be

Two slits are separated by distance of 0.5 and illuminate with light of lambda=6000Å . If the screen is placed 2.5m from the slits. The distance of the third bright image from the centre will be

Two slits separated by a distance of 1 mm are illuminated with light of wavelength 6.0 xx 10^-7 m . The interference fringes observed on a screen placed 1 m from the slits. The distance between third dark fringe and the fifth bright fringe is equal to :

Two slits separated by a distance of 1 mm are illuminated with red light of wavelength 6.5xx10^(-7) m. The interference firnges are observed on a screen placed 1 m form the slits. The distance between third bright firnge and the fifth dark fringe on the same side is equal to

In Young's double slit arrangement, slits are separated by a gap of 0.5 mm, and the screen is placed at a distance of 0.5 m from them. The distance between the first and the third bright fringe formed when the slits are illuminated by a monochromatic light of 5890 X is :

Two slits separated by a distance of 0.5 mm are illuminated by light of wavelength 5000 Å. The interference fringes are obtained on a screen at a distance of 1.2 m. what is the phase difference between two interfering waves at a point 3 mm from the central bright fringe?
