What negative visual effect is caused by curvature of field? aberration in lenses Curvature of field is present when the sharpest image is formed not on a flat plane but on a curved surface. Astigmatism occurs when the lens fails to focus image lines running in different directions in the same plane; in a picture […]
How can you tell if an Electroscope is positively or negatively charged?
How can you tell if an Electroscope is positively or negatively charged? Now the electroscope will allow you to identify whether an object is positively or negatively charged. If you bring a negative object near the electroscope, the electrons in the scope will be repelled toward the leaves, balancing the charge. The leaves will move […]
