What happens if white light is used in place of monochromatic light?

Explanation: 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 instead of monochromatic light in interference experiment?

In an interference experiment, monochromatic light is replaced by white light, we will see a few coloured bands and then uniform illumination.

What do you expect to see in the microscope if you use a white light source in Newton’s ring experiment?

When viewed with white light, it forms a concentric ring pattern of rainbow colors, because the different wavelengths of light interfere at different thicknesses of the air layer between the surfaces.

What will happen if we use white light in this experiment?

Newton’s rings scene in Plano-convex with their flat surface in contact.in white light the Rings are Rainbow colours because different wavelength of each colour interview at different location. when white light is used in Newton’s ring experiment circular rings of rainbow colour will appear….

Why monochromatic light is used in interference?

Monochromatic light ensures that the light is a single pure frequency. This ensures the peaks are equally spaced. Coherent light ensures all of the photons are in phase. This means for a single frequency all of the peaks and troughs will be lined up.

What is the difference between monochromatic light and white light?

Monochromatic means that all of the light produced by the laser is of a single wavelength. White light is a combination of all visible wavelengths (400 – 700 nm).

When interference of light takes place the intensity of light?

The light waves from two coherrent sources of same intensity I interfere. At the minimum, the intensity of light is zero.

What happen if we replace sodium light source by white light source?

What will happen when the sodium lamp is replaced by a white light source? Ans. A few coloured fringes are observed near the centre. The violet colour will come first as we proceed away from the centre.

What happens if we use white light in double-slit experiment?

If white light is used in the double-slit experiment, the different colours will be split up on the viewing screen according to their wavelengths. The violet end of the spectrum (with the shortest wavelengths) is closer to the central fringe, with the other colours being further away in order.

What is monochromatic beam of light?

A monochromatic light beam is characterized by its brightness or light intensity, direction of propagation, and color (all visible characteristics) and by its state of polarization (an invisible characteristic). Light waves oscillate, or swing back and forth, perpendicularly to the direction of propagation.

Can white light produce interference?

Yes, white light can produce interference pattern on the screen. When we observe the interference pattern then we see that all monochromatic ray are combined in fixed ratio.As the central part of bright fringe contain red light(deviates less) and at the both end violet(deviates more).

Is monochromatic light coherent?

Monochromatic light is coherent, if the waves of the monochromatic light oscillate in the same direction and have the same frequency and the same phase.

What happens when monochromatic light is replaced by white light?

White light consists of waves of inumerable wavelengths starting from violet to red colour. 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.

What change occurs if monochromatic light used in young’s double slit experiment?

>> What change occurs, if the What change occurs, if the monochromatic light used in Young’s double slit experiment is replaced by white light? All the bright fringes become white. When we use white light in place of monochromatic light then only central fringe looks white and other fringes of different colour are observed.

How to determine the wavelength of monochromatic light from concentric rings?

By studying the pattern of concentric rings, it is possible to determine the wavelength of monochromatic light and the refractive index of a given transparent liquid medium present in a wedge-shaped film.

Why does the central fringe of a light spectrum become white?

All the bright fringes become white. 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.
