Which of the following changes to a double-shift interference experiment with light would increase the widths of the fringes in the difference pattern that appears on the screen?
روشنی کے ساتھ ڈبل شفٹ مداخلت کے تجربے میں درج ذیل میں سے کون سی تبدیلی اسکرین پر ظاہر ہونے والے فرق کے پیٹرن میں کنارے کی چوڑائی کو بڑھا دے گی؟
- use light of a shorter wavelength
- move the screen closer to the slits
- move the slits closer together
- use light with a lower wave speed
- increase the intensity of the light
Explanation
by using light of a shorter wavelength in a double-slit interference experiment, the widths of the fringes in the resulting diffraction pattern on the screen would increase.
Concept and Explanation:
Wavelength of light:
The width of the fringes in a double-slit interference pattern is directly related to the wavelength of the light used.
When light with a shorter wavelength, such as blue or violet light, is used, the fringes in the resulting diffraction pattern will be wider compared to using light with a longer wavelength, such as red light.
This phenomenon can be explained by the diffraction of light waves.
Shorter wavelengths diffract more around obstacles and result in broader interference patterns on the screen.
