What else can I help you with?
Is a light pen mechanical or optical device?
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.
Why is a mirror an optical device?
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.
Is a laser an optical device?
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.
What is an optical device that is often used to refract white light called?
A prism. This will also split the white light. The prism is the most commonly used in experiments and demonstrations. However, there are other shaped tools that are sometimes used.
What optical device can produce a real image?
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.
