Explore how mirrors and lenses form images through reflection and refraction.
A plane mirror forms an image the same size as the object. Curved mirrors (concave or convex) can make images appear larger, smaller, or distorted.
Why do side mirrors on cars often say 'objects may be closer than they appear'?
These mirrors are convex, which makes objects appear smaller and farther away than they actually are
What type of image does a flat, plane mirror form — the same size, larger, or smaller than the object?
The same size as the object
A convex lens curves outward and can converge (focus) light rays, often used to magnify objects. A concave lens curves inward and spreads light rays apart.
What type of lens is used in a magnifying glass?
A convex lens
Why does a convex lens make small text appear larger when held close to a page?
It bends (refracts) light rays to converge, creating a magnified image of the text
