What happens if white light is used in YDSE?
Therefore, if monochromatic light in Young’s interference experiment is replaced by white light, then the waves of each wavelength form their separate interference patterns The resultant effect of all these patterns is obtained on the screen. Therefore, the central fringe is white.
What will happen when white light is used in why DSC?
When we use white light in place of monochromatic light then only central fringe looks white and other fringes of different colour are observed. It is becaused central fringe for all the colours are formed at central point so it becomes white after mixiing up.
What will happen if white light is used in Newton’s ring experiment?
If white light is used in the Newton’s rings experiment, the colour observed in the reflected light is complementary to that observed in the transmitted light is complementary to that observed in the transmitted light through the same point.
What are white light fringes?
For white light, we can consider that each wavelengths of the visible spectrum constitutes a system of superimposed fringes. As long as the optical path difference remains smaller than the coherence length of the source, the field appears as colored fringes (see figure 24) referred to as white light fringes.
Can you produce fringes with white light?
Yes, white light can produce interference. In this, each wavelength of white light produces its own interference pattern. If the angle of the fringes is large, fringes is large fringes overlap basically producing white light.
What kind of fringes do you expect to observe if white light is used instead of monochromatic light?
Thus if we use white light in place of monochromatic light the central fringe is white, containing on either side a few coloured fringes (in order VIBGYOR) and the remaining screen appears uniformly illuminated.
What is a white light source?
A white Light Source is a Light Source with a broad optical Bandwidth (usually 100 NM or more). They may contain something like a bulb (e.g. a tungsten Halogen lamp), emitting a smooth and very broadband optical spectrum. …
Which of the following is an example of a white light source?
The sun is the most obvious source of white light in our solar system. As for artificial sources, fluorescent light bulbs and white LEDs produce white light. Other light bulbs, like the incandescent lamp, do not produce white light. They produce light of much longer wavelengths along the yellow to red range.
