Question

For a point source, linear source and source situated at infinite, the shape of wave front is respectively:-

• A. Spherical, cylindrical, plane
• B. Cylindrical, spherical, plane
• C. Plane, spherical, cylindrical
• D. Spherical, plane, cylindrical

Answer 1

The correct option is A Spherical, cylindrical, plane

Point source produces$\to$ spherical wave front

Linear source produces $\to$ cylindrical wave front

Source situated at infinite distance produces $\to$ plane wave front
