Adjusting Camera Exposure and Focus

Camera In optics, an image is recreated by collecting some of the light emitted by an object. Devices that recognize images include eyes and cameras. The light entering the camera passes through the aperture and lens, … more

Light Refraction

Light Refraction

You can drag the path of light. Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another. This occurs because of the slow speed … more

Line Spectrum and Continuous Spectrum

Line Spectrum and Continuous Spectrum

A solid metal can be made by grouping several hot gaseous (monatomic) metals together. What is the difference between emission spectra in the gas (monatomic) and solid state? The simulation above is a simple example and … more
