In which mirror magnification is positive
WebRefracting Telescopes. The earliest telescopes, as well as many amateur telescopes today, use lenses to gather more light than the human eye could collect on its own. They focus the light and make distant objects appear brighter, clearer and magnified. This type of telescope is called a refracting telescope. Web30 mei 2024 · The virtual image is upright and the magnification is positive in this case. Is magnification negative in convex mirror? Magnification of a convex mirror is always positive , but that of a concave mirror may be both positive or negative . This magnification can tell us about the nature of the image based on the sign itself.
