Lenses and mirrors create images by manipulating light rays that enter them. Lenses refract, or bend, light rays while mirrors reflect them. This bending or reflection causes the light rays to converge or diverge, creating an image.
A convex lens is thicker in the middle and thinner at the edges, causing light rays to converge and form real images. A concave lens is thinner in the middle and thicker at the edges, causing light rays to diverge and form virtual images.
A convex lens would have a larger image because it causes light rays to converge, resulting in a magnified image. A concave lens would create a smaller, virtual image due to the divergence of light rays.
The size of an image created by a mirror can be determined by using the formula: image distance/object distance = image height/object height. The image distance is the distance between the object and the mirror, and the object distance is the distance between the mirror and the observer. This ratio will give the magnification of the image, which can be used to calculate the size of the image.
Yes, a concave mirror can create a real image under certain conditions. When the object is placed beyond the focal point of the mirror, the light rays will converge and form a real, inverted image. However, if the object is placed between the mirror and the focal point, the mirror will create a virtual, upright image.
