Question

In a Young’s double slit experiment, a source of wavelength 6000Å is used. The screen is placed 1m
from the slits. Fringes on the screen are observed by a student sitting close to the slits. The student’seye can distinguish two neighbouring fringes if they subtend an angle more than 1 minute of arc.
Calculate themaximumdistance between the slitsso thatfringes are clearly visible.Using thisinformation,
calculate the position of 3rd bright fringe and the 5th dark fringe from the centre of the screen.

Answer 1

Answer:

In a Young’s double slit experiment, a source of wavelength 6000Å is used. The screen is placed 1m

from the slits. Fringes on the screen are observed by a student sitting close to the slits. The student’seye can distinguish two neighbouring fringes if they subtend an angle more than 1 minute of arc.

Calculate themaximumdistance between the slitsso thatfringes are clearly visible.Using thisinformation,

calculate the position of 3rd bright fringe and the 5th dark fringe from the centre of the screen.
