If the magnification of a mirror or lens is negative it mean

If the magnification of a mirror or lens is negative, it means that the image is smaller than the object. the image is inverted and smaller than the object. the object is farther from the mirror (or lens) than the image. the image is farther from the mirror (or lens) than the object. the image is inverted. When light travels from air into water. its velocity changes, but its frequency and wavelength do not change. its frequency changes, but its velocity and wavelength do not change. its velocity and wavelength change, but its frequency does not change. its wavelength changes, but its velocity and frequency do not change. its velocity, wavelength and frequency all change. Two beams of coherent light start out at the name point in phase and travel different paths to arrive at point P. If the maximum constructive interference is to occur at point P, the two beams must travel paths that differ by a whole number of half-wavelengths. an odd number of half-wavelengths. a whole number of wavelengths. If you stand in front of a convex mirror, at the same distance from it as its radius of curvature, you won\'t see your image because there is none. you will see your image and you will appear smaller than you. you won\'t see your image because it is focused at infinity. you will see your image and it will be the same size as you except upside down. you will see your image and you will appear larger than you. If a object is placed between a convex lens and its focal point, the image formed is real and inverted. virtual and upright. virtual and inverted. real and upright.
