Step-by-step explanation:
To determine the distance between the bright interference fringes created by the laser beam incident on two slits, we can use the formula for the spacing between fringes in a double-slit interference pattern:
d = λL / (D * w)
Where:
- d is the distance between bright interference fringes (also known as the fringe spacing)
- λ is the wavelength of the light (632.8 nm)
- L is the distance from the double-slit to the screen (the distance at which the interference pattern is observed)
- D is the distance between the two slits (0.200 mm or 0.200 × 10^-3 m)
- w is the order of the fringe (for the bright fringes, w = 1)
Plugging in the values into the formula:
d = (632.8 nm) * L / [(0.200 × 10^-3 m) * 1]
To find the distance between bright interference fringes, we need the value of L (distance from the double-slit to the screen). Without that information, we cannot determine the exact value of d.
