Single Slit Diffraction — MCQ Practice

In a single-slit diffraction experiment, the width of the central maximum is $W$. If the slit width is doubled, and the wavelength of light is halved, what will be the new width of the central maximum?

In a single-slit diffraction pattern, the angular width of the central maximum is $Delta\theta$. If the entire apparatus is immersed in water (refractive index $mu = 4/3$), what will be the new angular width of the central maximum?

In a single-slit diffraction pattern, the first minimum for light of wavelength $600,\text{nm}$ occurs at an angle of $30^circ$. What is the width of the slit?

Which of the following statements is TRUE regarding the intensity distribution in a single-slit diffraction pattern?

A single slit of width $0.5,\text{mm}$ is illuminated by light of wavelength $5000,mathring{\text{A}}$. What is the angular position of the second minimum?

If a single-slit diffraction experiment is performed using red light instead of blue light, how will the diffraction pattern change?
