Lighting up matchstick with magnifying glass .
The light rays is refracted when they reach the glass and it is focus on one direction which is the matchstick and the heat lights it up .
How does a magnifying glass work
A magnifying glass is simply a convex lens meant to be held up to an object to see it magnified. This shape bends the light waves of objects viewed through it, causing us to see them in unusual ways. When you hold a magnifying glass close to an object, its light waves are widened before they are focused on your eyes, causing the object to appear very large. But when you hold a magnifying glass out and view a distant object with it, the item appears smaller and upside down. This effect is due to the image being beyond the focus of the lens. The more curved a convex lens is, the greater its ability to bend light and magnify.
How Does A Magnifying Glass Work?

The distance between the lens and the object must be shorter than the focal length of the lens for this to occur. Otherwise, the image appears smaller and inverted, and can be used to project images onto surfaces.

The magnifying glass refracts the ray to a point called focal point. It is where the rays coming from the Sun in a parellel manner gets refracted into the focal area. The heat from the Sun also gets refracted to that focal area. Thus, fire can be ignited through maginifying glass.

light up matches with magnifing glass
Light emitted by the sun is made up of tiny packets of electromagnetic energy.the rays are refracted and due to the rays of light and its ability change angle as they pass through the lens and meet at a specific point.also with the preasence of oxygen,a fire is lit up.
