Difference between real and virtual image

real inverted. can be projected onto a screen. is inverted with the respect to the object is on the same side of the mirror as object can be larger, smaller, or the same size as the object. rays of light actually converge and pass through the image virtual Upright Cannot be projected on the screen The location of reflected image is behind the mirror is formed by convex mirror can be smaller, or the same size as the object. rays of light do not actually pass through the image. cannot be formed on a screen. is inverted with the respect to the object can be projected onto a screen. is on the same side of the mirror as object is formed by concave mirror can be larger, smaller, or the same size as the object. rays of light actually converge and pass through the image can be formed on a screen.

Plane mirror Forms images that are….. the same size as the object only. The location is behind the mirror always the same distance from the mirror as the object. have left to right reversal. only virtual. always upright is flat, smooth mirror. Concave mirror Forms images that are….. either smaller/same size/larger than the object. either behind the mirror or on the same side as the object. either real or virtual. upright or inverted. is a curved mirror. Forms images that are….. always reduced. only virtual. always upright is a curved mirror. convex mirror

Convex lens In the convex lens….. the curve faces outward is a converging lens that spreads out the light. is thicker at the center, as compared to its edges. is use for correction of farsightedness or hyperopia. is called positive lens because of its positive focal length nature. Concave lens In the concave lens….. the curve faces inward. is thinner at the center, as compared to its edges. is use for correction of nearsightedness or myopia. is a diverging lens which converges the refracted rays. is called negative lens because of its negative focal length nature.
