For what distance is ray optics, a good approximation when a plane light wave is incident on a circulation aperture of width 2 mm having wavelength 600 nm ?

Text Solution

Verified by Experts

Ray optics is a good approximation upto Fresnel distance only.
`Z_F=a^2/lamda=(2 times 10^-3)^2/((600 times 10^-9))=6.7 m`
Hence, the ray optics hold good upto distance of 6.7 m.
