What is the normal distance for viewing the virtual image on a 15-20 inch TV monitor?

The normal viewing distance for a virtual image on a 15-20 inch TV monitor is typically in the range of 12-15 inches. This distance ensures that the viewer can comfortably focus on the screen without straining their eyes. Viewing from this range allows for optimal image quality and clarity, as it balances the size of the screen and the viewer's ability to perceive detail.

Maintaining this distance is important because sitting too close can lead to visual discomfort, while sitting too far away may make it difficult to see finer details. In medical imaging and fluoroscopy contexts, where precision and clarity are vital, adhering to recommended viewing distances helps to ensure both effective communication of information and the viewer's comfort during examinations.
