Monochromatic light from a narrow slit illuminates two narrow slits 0.3 mm apart, producing an interference pattern with bright fringes 1.5 mm apart on a screen 75 cm away. Find the wavelength of the light. Find the fringe width if (a) the distance of the screen is doubled and (b) the separation between the slits is doubled?

Q. Monochromatic light from a narrow slit illuminates two narrow slits 0.3 mm apart, producing an interference pattern with bright fringes 1.5 mm apart on a screen 75 cm away. Find the wavelength of the light. Find the fringe width if (a) the distance of the screen is doubled and (b) the separation between the slits is doubled?

Q. In a Young's double - slit experience, the slits are 2mm apart and are illuminated with a mixture of two wavelengths ${\lambda }_0=750nm$ and $\lambda =900nm$. The minimum distance from the common central bright fringe on a screen 2 m away from the slits where a bright fringe from one interference pattern coincides with a bright fringe from the other, is

Q. In a Young's double - slit experience, the slits are 2mm apart and are illuminated with a mixture of two wavelengths ${\lambda }_0=750nm$ and $\lambda =900nm$. The minimum distance from the common central bright fringe on a screen 2 m away from the slits where a bright fringe from one interference pattern coincides with a bright fringe from the other, is

Q. In Young's double slit experiment, the two slits $0.15$mm apart are illuminated by monochromatic light of wavelength $450$nm. The screen is $1.0$m away from the slits. (a) Find the distance of the second. (I) bright fringe, (ii) dark fringe from the central maximum, (b) How will the fringe pattern change if the screen is moved away from the slits?

Q. In a Young's double slit experiment, the slits are $2mm$ apart and are illuminated with a mixture of two wavelength ${\lambda }_0=750nm$ and $\lambda =900nm$ . The minimum distance from the common central bright fringe on a screen 2 m from the slits where a bright fringe from one interference pattern coincides with a bright fringe from the other is
