283095 A single slit of width a is illuminated by violet light of wavelength \(400 \mathrm{~nm}\) and the width of the diffraction pattern is measured as \(y\). When half of the slit width is covered and illuminated by yellow light of wavelength \(600 \mathrm{~nm}\), the width of the diffraction pattern is :

1 the pattern vanishes and the width is zero
2 \(y / 3\)
3 \(3 \mathrm{y}\)
4 none of these
