Angle of reflection diagram2/20/2023 Images produced by plane mirrors have a number of properties, including: All objects obey the law of reflection on a microscopic level, but if the irregularities on the surface of an object are larger than the wavelength of light, which is usually the case, the light reflects off in all directions.Ī plane mirror is simply a mirror with a flat surface all of us use plane mirrors every day, so we've got plenty of experience with them. Most objects exhibit diffuse reflection, with light being reflected in all directions. All the light travelling in one direction and reflecting from the mirror is reflected in one direction reflection from such objects is known as specular reflection. Reflected light obeys the law of reflection, that the angle of reflection equals the angle of incidence.įor objects such as mirrors, with surfaces so smooth that any hills or valleys on the surface are smaller than the wavelength of light, the law of reflection applies on a large scale. Objects can be seen by the light they emit, or, more often, by the light they reflect. In particular, we'll use rays and wave fronts to analyze how light interacts with mirrors and lenses. Rays and wave fronts can generally be used to represent light when the light is interacting with objects that are much larger than the wavelength of light, which is about 500 nm. If the source is a long way away, the wave fronts can be treated as parallel lines. For a source like the Sun, rays radiate out in all directions the wave fronts are spheres centered on the Sun. A wave front is the line (not necessarily straight) or surface connecting all the light that left a source at the same time. A ray is a thin beam of light that travels in a straight line. Light is a very complex phenomenon, but in many situations its behavior can be understood with a simple model based on rays and wave fronts.
