State true (T) or false (F).
(a) A virtual image can be obtained on a screen.
(b) The image formed by a plane mirror is inverted.
(c) The image formed by a plane mirror is laterally inverted.

Explanation

**Step-by-Step Solution:**

1. **Statement (a):** "A virtual image can be obtained on a screen."
- **Analysis:** A virtual image is formed when the rays of light appear to diverge from a point behind the mirror or lens. In reality, these rays do not converge at that point; they only seem to do so when extended backward. Since a screen requires the actual convergence of light rays to display an image, a virtual image cannot be projected onto a screen.
- **Conclusion:** This statement is **False (F)**.

2. **Statement (b):** "The image formed by a plane mirror is inverted."
- **Analysis:** An inverted image means that the top and bottom of the image are switched. However, the image formed by a plane mirror is not inverted in this way; it maintains the same orientation with respect to top and bottom. The image is, however, laterally inverted, meaning the left and right sides are swapped.
