What does the work laser stand for?
The term "laser" stands for "Light Amplification by Stimulated Emission of Radiation." It describes a device that emits a narrow and intense beam of light through the process of optical amplification based on the stimulated emission of electromagnetic radiation.
How do you use optical in a sentence?
That laser light really did damage my optic nerve.
Does optical disk use laser beam?
Yes, optical disks use a laser beam to read and write data on the disk. The laser beam is focused onto the surface of the disk to detect and interpret the patterns of pits and lands that represent the data stored on the disk.
How does optical lever work?
An optical lever works by using a laser beam and a mirror attached to the system being measured. As the system moves, it changes the angle of reflection of the laser beam on the mirror. By measuring this change in the laser beam's position, the displacement of the system can be accurately determined.
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.
