Zoom, or magnification, refers to the process of enlarging an image or object to see more detail. This technique is commonly used in photography, where a camera can zoom in on a subject, making it appear larger and clearer. It allows us to explore tiny details that are not visible to the naked eye, enhancing our understanding of the world around us. In addition to photography, zoom is also essential in fields like microscopy and astronomy. For instance, a telescope can zoom in on distant stars and planets, revealing their features. Similarly, a microscope magnifies small specimens, enabling scientists to study cells and microorganisms in great detail.
