Young's experiment aimed at observing interference of light waves. To observe clear interference patterns it is necessary to use monochromatic sources.
Using monochromatic sources are coherent with constant phase difference so the interference pattern remains same on screen with passage of time. But using just any source will give a changing phase difference and a changing interference pattern which is difficult to observe.

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 is monochromatic source?
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.
Why ordinary light is not used for the experiment diffraction grating?
Ordinary light is not used for diffraction grating experiments because it is not monochromatic, meaning it consists of multiple colors (wavelengths). A monochromatic light source, such as a laser, is required for diffraction grating experiments to produce clear and precise interference patterns.
What is the nature of source of light use in diffraction grating?
The source of light used in a diffraction grating is typically a monochromatic and collimated light source, such as a laser. This type of light source emits a single wavelength of light in a narrow, parallel beam which is important for producing sharp and distinct diffraction patterns.
Why are two independent sources of light used to illuminate the two slits in Young's double slit experiment?
You have to correct the question as,Why are two independent sources of light not used to illuminate the two slits in Young's double slit experiment?We need coherent sources. But two independent sources would emit waves with varying phase difference which makes waves non coherent.

Is hydrogen light a monochromatic source?
Hydrogen light is not completely monochromatic as it consists of multiple spectral lines. However, the most prominent and widely used line is the hydrogen-alpha line at a wavelength of approximately 656.3 nm, which is often used in astronomy and other scientific applications.
What type of light source is typically used in a polarimeter to measure the rotation of polarized light?
A polarimeter typically uses a monochromatic light source, such as a sodium lamp or a laser, to measure the rotation of polarized light.
What is meant by polychromatic source?
A polychromatic source is a light source that emits several colors or wavelengths of light simultaneously. It is different from a monochromatic source, which emits light of a single color or wavelength. Polychromatic sources are commonly used in applications such as photography, microscopy, and lighting design.

Can you give a sentence for the word monochromatic?
This place used to be so colourful, but now they have painted it all the same colour it is drab and monochromatic.

What is monochromatic in physics terms?
In physics, monochromatic refers to light that consists of only one wavelength. This means that the light is of a single color with a specific frequency. Monochromatic light is often used in experiments and applications that require precise and controlled wavelengths.
What is a pharyngeal gill?
Pharyngeal slits are not gill slits. They are filter-feeding organs in non-vertebrates, and are used to strain matter and food from water.
