Question

If a light is passed through a single-slit hole and falls onto a screen . Identify the pattern of light produced on the screen :

• A. alternating bright and dark lines of equal width
• B. a bright central band of light with much smaller, dimmer bands toward the edges
• C. concentric circles of light
• D. one circle of light
• E. one bend of light

Answer 1

The correct option is B a bright central band of light with much smaller, dimmer bands toward the edges

Diffraction of light takes place when it is passed through a small hole or a slit.

When it is passed through a small hole the emergent waves propagate towards the screen and forming bright and dark fringes due to interference of diffracted light at different angles, with intensity of light decreasing as one goes to higher order bands.
