What is a dark sensor?
A sensor that is activated by a lack of light (the dark). Usually these can be found in night lights that turn on when the lights are turned out.
What is Three dark lamps method?
There are 3 darks lamps that people use as light when they do it HARD
Why don't transition lenses get dark in hot weather?
What some people call Transitions, a registered trademark, lens are designed and built to react to light levels. Low light the lens stay transparent, when bright light hits the lens the way the lens are made makes the lens change to the apropriate level of dark in a fraction of a second.
What is it called when a background fades from light to dark?
It is called modal in HTML & CSS world! I hope this was the answer you were looking for!
What type of circuit normally contains LDR?
LDRs are normally found in Light/Dark sensing circuits
How is interference in light recognized?
by the light and dark spots (fringes)
What do you mean by diffraction?
• DIFFRACTIONDIFFRACTION has 1meaning:When light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands
Why is an extended source used in newtons ring experiment?
extende source is required to get nearly parallel rays of light
Why there are dark and bright fringes on the screen of ripple tank?
123
What will be the resulting spectrum if use a monochromatic light instead of sodium vapour lamp in diffraction grating?
You will observe a series of bright and dark fringes uniformly spaced, of the color of the monochromatic light used.
What is the discovery of Thomas Young about light?
thomas young carried out his (double slit experiment) where he discussed the interference of light waves using monochromatic light . the 2 slits act as 2 coherent sources which emit light with same amplitude frequency . interference fringes appear due to superposition of light . this experiment is also used to determine the wavelength of monochromatic light. from the relation y=wavelength*distance between 2 slits /distance between the 2 slits and the screen where the fringes appear . where y is the distance between 2 successive bright or dark fringes.
What conditions are necessary for two light waves to form an interference pattern of bright lines and dark areas?
State two necessary conditions for formation ofinterference fringes.
Why does light produce a pattern similar to an interference pattern when it passes through a single slit?
This phenomenon occurs due to light's wave-like properties. Via diffraction, the bending of light wave about an obstacle, the light wave will interfere and exhibit dark and bright fringes on a screen as a result of this interference.
What is interfere pattern?
sustained interference are those in which the position of bright and dark fringes are fixed on the screen.
What are conditions for a bright and a dark fringe?
central maximum is double the with of any other fringe. all other fringes(dark and bright) are of the same width.
What is sustained interference pattern?
sustained interference are those in which the position of bright and dark fringes are fixed on the screen.
What is meant by fringe width?
Fringe-width is defined as the sepration between two consecutive dark or bright fringes on the screen.
