Light of wavelength `5 xx 10^(-7)m` is diffracted by an aperture of width `2 xx 10^(-3)m`. For what distance travelled by the diffrated beam does the spreading due to diffraction become greater than width of the aperture ?

Text Solution

AI Generated Solution

To solve the problem, we need to determine the distance traveled by the diffracted beam at which the spreading due to diffraction exceeds the width of the aperture. We will use the formula for the fractional distance \( f_z \) given by: \[ f_z = \frac{a^2}{\lambda} \] where: - \( a \) is the width of the aperture, ...
