Modifying Slit Separation for Seeing Fringes Again | 65 Characters

In summary, the conversation discusses how the resolving power of eyes is affected by the slit separation and how the wavelength of light must be adjusted to maintain a certain theta for clear visibility of fringes. The solution suggests increasing the wavelength to achieve a larger theta, while the book presents different ideas.

Homework Statement


i can't understand part b ii) , i assume the resolving power of eyes is constant . so when the slit separation increase , the wavelength of the light should be decreased to keep the tetha ( here , tetha = resloving power of eyes in radian )...But the book give different ideas . Can someone explain on this?

The fringes are formed closer together when the slits are further apart.
The solution calculates when they will just be resolved by the eye, but
not seen "clearly". That is theta need to be increased even more to be
able to see the fringes clearly. If the same double slit is to be used all
that can be done is to increase the wavelength to obtain a larger theta.

Related to Modifying Slit Separation for Seeing Fringes Again | 65 Characters

What is the purpose of modifying slit separation for seeing fringes again?

The purpose of modifying slit separation for seeing fringes again is to improve the resolution and clarity of the fringes in an interference pattern. By altering the distance between the slits, the resulting fringes can become more visible and easier to analyze.

How do you modify slit separation for seeing fringes again?

To modify slit separation for seeing fringes again, you can physically adjust the position of the slits or use a device such as a micrometer to make precise changes. It is important to carefully measure and record the distance between the slits to ensure accurate modifications.

What factors affect the visibility of fringes in an interference pattern?

The visibility of fringes in an interference pattern can be affected by several factors, including the wavelength of the light, the distance between the slits, and the angle of incidence. Changes in any of these variables can impact the clarity and intensity of the fringes.

Are there any limitations to modifying slit separation for seeing fringes again?

Yes, there are limitations to modifying slit separation for seeing fringes again. The distance between the slits cannot be reduced to zero, as this would result in a single-slit diffraction pattern instead of an interference pattern. Additionally, changing the distance between the slits may also affect the overall intensity of the light in the pattern.

Why is it important to see fringes in an interference pattern?

Seeing fringes in an interference pattern is important because it allows scientists to study the properties of light and make precise measurements. Interference patterns can also be used to determine the wavelength of light and detect tiny variations in distance or motion. Additionally, interference patterns are used in various technologies, such as holography and interferometry.
