Question

Will the diffraction effects from a slit be more or less clearly visible if the slit-width is increased?

Answer 1

Diffraction refers to various phenomena that occur when a wave encounters an obstacle or a slit. ... While diffraction occurs whenever propagating waves encounter such changes, its effects are generally most pronounced for waves whose wavelength is roughly comparable to the dimensions of the diffracting object or slit.

Answer 2

Diffraction is the process by which a beam of light waves spread out as a result of passing through a narrow aperture or across an edge.

Width of central Diffraction Band =2D λ/2

where d is the width of slit

.

• From the above equation we can say that The width of the central band is inversely proportional to the slit width.

• So, as the width of the slit is increased, the central band will become less wider and further bands will start merging in them.

• Hence, diffraction effects will be visible less clearly.
