Homework Statement
Hi,
For the Young double slit experiment, say I have a plane wavefront approaching the double slit; now, if I halve the width of one of my slits, will the amplitude of the light exiting that slit be halved as well?
Homework Equations
None directly relevant I know of, but related:
Intensity directly proportional to [amplitude]2
nλ=dsinθ
λ=(ax)/D
The Attempt at a Solution
So I thought that, as the slit width is really very close to the wavelength of light itself, that halving would have a noticeable impact on the amplitude? But I also wondered whether making it much smaller than the wavelength of light as a result would completely block out the light anyway??
Thanks for your help!
