Draw a ray diagram to show the formation of an image when the object is placed between the C and F points of a concave mirror.

Sure, here are the steps to draw a ray diagram when the object is placed between the C (center of curvature) and F (focus) points of a concave mirror:

1. Draw a straight horizontal line to represent the principal axis.

2. Draw a concave mirror on the principal axis. The mirror should look like a "U" shape.

3. Mark the center of the mirror as 'P' (pole), the focus point as 'F' and the center of curvature as 'C'. The points F and C should be on the left side of P (assuming the mirror is facing to the right).

4. Draw an object between C and F. The object can be represented as an arrow perpendicular to the principal axis.

5. Draw a ray parallel to the principal axis from the top of the object to the mirror. This ray, after reflection, will pass through the focus (F).

6. Draw another ray from the top of the object, passing through the center of curvature (C). This ray, after hitting the mirror, will reflect back along the same path.

7. The point where the two reflected rays intersect will be the top of the image. Draw an arrow from this point to the principal axis. This arrow represents the image of the object.

8. The image formed will be inverted and larger than the object, which is a characteristic of images formed by concave mirrors when the object is placed between the center of curvature and the focus.
