Rays diverge from a point source of a wavefront that is

Options

A. Cylindrical
B. Spherical
C. Plane
D. Cubical

Answer

To solve the question regarding the nature of the wavefront from a point source, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Point Source**:
- A point source emits waves in all directions. This means that the rays of light or waves will spread out from the source.

2. **Definition of Wavefront**:
- A wavefront is defined as the locus of all points that are in the same phase of the wave. This means that at any given moment, all points on the wavefront are oscillating together.

3. **Identifying the Shape of the Wavefront**:
- Since the rays are diverging from a single point source, we need to determine the shape of the wavefront that corresponds to this divergence.
- As the waves spread out uniformly in all directions from the point source, the wavefront will take the shape of a sphere.

4. **Conclusion**:
- Therefore, the wavefront produced by a point source is spherical. The rays diverge from the point source and form a spherical wavefront.

5. **Final Answer**:
- The correct answer is that rays diverge from a point source of wavefront that is **spherical**.
