WebThe object is the source of the incident rays and the image is formed by the reflected rays. Based on the intersection of light rays, the images are classified as either a real images or a virtual images. A real image occurs when the light rays actually intersect while virtual images occur due to the apparent divergence of light rays from a point. WebLight travels as transverse waves and faster than sound. It can be reflected, refracted and dispersed. Ray diagrams show what happens to light in mirrors and lenses. Eyes and …

WebUpon reflecting, the light will converge at a point. At the point where the light from the object converges, a replica or likeness of the actual object is created; this replica is known as the image. Once the reflected light rays reached the image location, they begin to diverge. WebJul 16, 2024 · Light is a form of energy that travels as waves. Their length — or wavelength — determines many of light’s properties. For instance, wavelength accounts for light’s color and how it will interact with matter. The range of wavelengths, from super short to very, very long, is known as the light spectrum.
