Question on: SS3 Physics - Light Waves II

Optical instruments use the principles of light wave behaviour to manipulate and control the path of light. Some common examples of optical instruments include telescopes, microscopes, cameras, and lenses. Telescopes are used to observe and study celestial objects such as stars and planets, while microscopes are used to study small structures such as cells and microorganisms. Cameras use lenses and light-sensitive materials to capture images, and lenses are used in eyeglasses, contact lenses, and other vision correction devices.
