for double slit diffraction, the bright fring appears at m*wavelength*screen distance/slit width
where m=order of the bright fringe
so putting the given values,we get for m=1,2 and 3, the distances are 6m, 12 m and 18 m
B)width of the band=wavelength*distance of screen/slit width=6 m
C) as intensity decrease with distance, the band at 6 m is brightest and band at 18 m is least bright.

4. (10 points) Laser light is shone through a slide containing a double slit onto a screen 330 cm away. The distance between the slits is 255 um. the distance between adjacent bright regions is 6.25 mm. What is the wavelength of the laser? Give your answer in nano-meters.
A double-slit interference pattern is created by two narrow slits spaced 0.30 mm apart. The distance between the first and the fifth minimum on a screen 40 cm behind the slits is 6 mm. What is the wavelength of the light used in this experiment?
A double-slit interference pattern is created by two narrow slits spaced 0.22 mm apart. The distance between the first and the fifth minimum on a screen 58 cm behind the slits is 6.3 mm. What is the wavelength (in nm) of the light used in this experiment?
A double-slit interference pattern is created by two narrow slits spaced 0.22 mm apart. The distance between the first and the fifth minimum on a screen 58 cm behind the slits is 6.1 mm. What is the wavelength (in nm) of the light used in this experiment?
A double-slit interference pattern is created by two narrow slits spaced 0.21 mm apart. The distance between the first and the fifth minimum on a screen 62 cm behind the slits is 6.0 mm. What is the wavelength (in nm) of the light used in this experiment? λ = ( )nm
A double - slit interference pattern is created by two narrow slits spaced 0.20 mm apart. The distance between the first and the fifth minimum on a screen 62 cm behind the slits is 5.9 mm. What is the wavelength (in nm) of the light used in this experiment? Express your answer to two significant figures and include the appropriate units.
3. When a monochromatic light source shines through a 1 mm wide slit onto a screen 7 m away, the first dark band in the pattern appears 4 mm from the center of the bright band. What is the wavelength of the light? What color is it? If instead of a single slit, you had two slits separated by 1 mm, what would you see?
A single-slit diffraction pattern (c24p28) A single-slit diffraction pattern is formed when light of = 587.0 nm is passed through a narrow slit. The pattern is viewed on a screen placed one meter from the slit. What is the width of the slit (mm) if the width of the central maximum is 2.43 cm? Submit Answer Incorrect.

Laser light of wavelength 633 nm falls onto a double slit with slit separation 0.132 mm. An interference pattern is observed on a screen 2.20 m away. How far apart are the bright spots on the screen near the middle of the pattern?
Two narrow slits are used to produce a double-slit interference pattern with monochromatic light. The slits are separated by 7 mm, and the interference pattern is projected onto a screen 7 m away from the slits. The central bright fringe is at a certain spot on the screen. Using a ruler with one end placed at the central fringe, you move along the ruler passing by two more bright fringes and find that the next bright fringe is 21.5 mm...
