Q: Lets suppose a plane wave is passing through a variable square opening. The diff

from the fomrula of diffraction patterns Y = mLR/d Y is fringe width L is wavelength R is disatnce d is distance from slit to screen so to have diffraction patterns so here the answers are a, and B are true

Question

Lets suppose a plane wave is passing through a variable square opening. The diffraction becomes important in which of the following situations? a.the beam is coherent b. one or more dimensions of the rectangular opening is near the wavelength of the source c.both dimensions of the rectangular opening are larger than the wavelength of the source d.only if the opening is circular Lets suppose a plane wave is passing through a variable square opening. The diffraction becomes important in which of the following situations? a.the beam is coherent b. one or more dimensions of the rectangular opening is near the wavelength of the source c.both dimensions of the rectangular opening are larger than the wavelength of the source d.only if the opening is circular

Explanation / Answer

from the fomrula of diffraction patterns Y = mLR/d

Y is fringe width

L is wavelength

R is disatnce

d is distance from slit to screen

so to have diffraction patterns

so here the answers are

a, and B are true
