A convex lens is a type of lens that is thicker in the middle than at the edges. It converges light rays that are coming in parallel to its principal axis. Here are some key points about convex lenses:

▎Properties of Convex Lenses:

1. Convergence of Light: When parallel rays of light pass through a convex lens, they converge at a point called the focal point.

2. Focal Length: The distance from the center of the lens to the focal point is known as the focal length. It is positive for convex lenses.

3. Image Formation:

• Real Images: When the object is placed outside the focal length, a real and inverted image is formed on the opposite side of the lens.

• Virtual Images: If the object is placed within the focal length, a virtual and upright image is formed on the same side as the object.

4. Magnification: The magnification produced by a convex lens can be calculated using the formula:

Magnification (m) = Height of Image (h') / Height of Object (h} = v / u


where v is the image distance and u is the object distance.

▎Applications of Convex Lenses:

1. Eyeglasses: Used to correct hyperopia (farsightedness).

2. Cameras: Convex lenses are used to focus light onto film or sensors.

3. Microscopes and Telescopes: They help magnify small objects or distant celestial bodies.

4. Projectors: Used to project images onto a screen.

▎Lens Formula:

The relationship between object distance (u), image distance (v), and focal length (f) of a lens is given by the lens formula:

1 / f = 1 / v - 1 / u


▎Sign Convention:

• Object distance (u) is taken as negative when measured from the lens towards the object.

• Image distance (v) is positive for real images and negative for virtual images.

• Focal length (f) is positive for convex lenses.
