A light pen is an optical device that detects light emitted by a computer screen to determine the position of the pen on the screen. It is used as an input device to interact with computers by pointing, clicking, and drawing on the screen.
A camera is an optical device that can produce a real image. It does this by focusing light onto a photosensitive surface (like film or a digital sensor) to create a true-to-life representation of the scene being captured.
A magnifying glass is an optical device that can produce a virtual image by magnifying an object placed beneath it. The image appears larger and at a different location, appearing to be virtual and upright.
A mirror is an optical device because it reflects light, forming an image by reflection. It works on the principle of specular reflection, where light rays are reflected at the same angle as they strike the mirror surface. This reflection process allows mirrors to create virtual images that can be seen by the human eye.
Yes, a laser is an optical device that emits a narrow beam of coherent light through the process of stimulated emission of photons. It is used in a wide range of applications including cutting, welding, communication, and medical procedures.
No, its not an optical storage device.
It is not an optical device. C D ROM or DVD are optical devices. Whereas a digital memory card is solid state device.
It is an optical device to study about the spectrum produced by the refraction phenomenon through a triangular prism or obtained by the diffraction phenomenon at the grating.
magnetic storage device
It's input I think, not that sure, but I just know that it reads data from a disc and then views them onto the computer screen. :)
