How will the diffraction pattern change when yellow light is replaced by blue light? The fringes will be

$A$ single slit diffraction pattern is formed with white light. For what wavelength of light, the $3^{\text{rd}}$ secondary maximum in the diffraction pattern coincides with the $2^{\text{nd}}$ secondary maximum in the pattern of red light of wavelength $6000 \text{ Å}$ (in $\text{ Å}$)?

In a single-slit diffraction experiment,if the width of the slit is reduced,what happens to the linear width of the principal (central) maxima?

Ray optics fails when

Angular width $(\beta)$ of the central maximum of a diffraction pattern on a single slit does not depend upon

$A$ light wave is incident normally on a slit of width $24 \times 10^{-5} \, cm$. The angular position of the second dark fringe from the central maximum is $30^\circ$. What is the wavelength of light in $\mathring{A}$?
