Solution

The correct option is B
one wide slit

Diffraction pattern cannot be observed with one wide slit. When the size of the slit is large (a > λ), bending of light becomes so small that it cannot be detected upto a certain distance of screen from the slit. Hence no diffraction

A parallel beam of light of 600 nm falls on a narrow slit and the resulting diffraction pattern is observed on a screen 1.2 m away. It is observed that the first minimum is at a distance of 3mm from centre of the screen. Calculate the width of the slit.

A parallel beam of light of wavelength 500 nm falls on a narrow slit and the resulting diffraction pattern is observed on a screen 1 m away. It is observed that the first minimum is at a distance of 2.5 mm from the centre of the screen. Find the width of the slit.

Q. Monochromatic light from a narrow slit illuminates two narrow slits 0.3 mm apart, producing an interference pattern with bright fringes 1.5 mm apart on a screen 75 cm away.
