In Young’s double slit experiment, using light of wavelength 600 nm, `10^(th)` bright fringe is obtained on a screen, 3mm from the centre of the pattern. If the screen is 120 cm away from the slits, calculate:
(i) Distance between the two slits,
(ii) Fringe width, i.e. fringe separation.

In Young.s double slit experiment using monochromatic light of wavelength 600 nm, 5th bright fringe is at a distance of 0.48 mm from the centre of the pattern. If the screen is at a distance of 80 cm from the plane of the two slits, calculate : Distance between the two slits.

In Young.s double slit experiment using monochromatic light of wavelength 600 nm, 5th bright fringe is at a distance of 0.48 mm from the centre of the pattern. If the screen is at a distance of 80 cm from the plane of the two slits, calculate : Fringe width, i.e., fringe separation.

In double slit experiment using light of wavelength 600 nm , the angular width of a fringe formed on a distant screen is 0.1^(@) . What is the spacing between the two slits ?

In Young's double slit experiment, when light of wavelength 4000 A^(@) is used 90 fringes are seen on the screen. When light of 3000 A is used, the number of fringes seen is

(a) In Young.s double slit experiment using monochromatic light of wavelength 600 nm, interference pattern was obtained on a scren kept 1.5 m away from the plane of the two slits. Calculate the distance between the two slits. Fringe "separation" // "fringe" width was found to be 1.0 mm. (b) When a fish is observed underwater at depth of 3 m appears to be at a depth of 2 m. What is the refractive index of water ?

Laser light of wavelength 630 nm is incident on a pair of slits which are separated by 1.8 mm. If the screen is kept 80 cm away from the two slits, calculate : fringe separation i.e., fringe width

In Young.s double slit experiment, using monochromatic light, fringes are obtained on a screen placed at some distance from the slits. If the screen is moved by 5 xx 10^(-2) m towards the slits, the change in the fringe width is 3 xx 10^(-5) m. If the distance between the two slits is 10^(-3)m , calculate wavelength of the light used.

In Young's double slit experiment, the fringe width with light of wavelength 6000 Ã… is 3 mm. The fringe width, when the wavelength of light is changed to 4000 Ã… is

In young's double slit experiment with monochromic light, fringes are obtained on a screen placed at some distance from the plane of slits. If the screen is moved by 5 cm towards the slits, then the change in fringe width is 30mum if the distance between the slits is 1mm, then calculate wavelength of the light used.
