Shape of the wave front of light emerging out of a convex lens when a ...
Explanation:
When a point source is placed at the focus of a convex lens, the emerging wave front of light will be plane. This can be explained using the following points:
Working:
When a point source is placed at the focus of a convex lens, the light rays emerging from the lens will be parallel to each other. This is because the convex lens converges the light rays that pass through it. When the light rays converge at the focus, they become parallel to each other.
Since the light rays are parallel to each other, the wave front of light emerging from the lens will be a plane surface. This is because all the points on the wave front have the same phase and are equidistant from the source.
Therefore, the correct answer is option B, plane.
When a point source is placed at the focus of a convex lens, the emerging wave front of light will be plane. This can be explained using the following points:
- Definition: A wave front of light is a continuous and connected surface of points where the phase of all points is the same.
- Convex Lens: A convex lens is thicker in the middle and thinner at the edges. It is also known as a converging lens because it converges the beam of light passing through it.
- Focus: The focus of a convex lens is a point on the principal axis where all the parallel rays of light converge after passing through the lens.
- Point Source: A point source is a source of light that emits light in all directions from a single point.
