No, a concave lens cannot start a fire with the aid of the sun. Concave lenses cause light rays to diverge, which would spread the sunlight out rather than concentrate it to create enough heat to start a fire. For starting a fire with a lens, a convex lens or a magnifying glass is usually used to focus sunlight to a point.
What else can I help you with?
Why do objects appear closer that it really is when viewed through a convex lens?
A convex lens converges light rays towards a point known as the focal point, causing the image to appear magnified. As a result, objects viewed through a convex lens may seem closer than they actually are due to the way the lens refracts light. This magnification effect is utilized in magnifying glasses and corrective lenses to aid in vision.
What is the function of a magnifying lens?
A magnifying lens is used to make objects appear larger than they actually are by bending light rays as they pass through the lens. This is achieved by the lens's convex shape, which causes the light rays to converge towards a focal point, magnifying the image. Magnifying lenses are commonly used for tasks that require close-up inspection or to aid in reading small text.
