Young's Double-Slit Interference: Exploring Light Patterns

How far apart are the fringes in the center of the pattern on a screen 4.1 m away?

What phenomenon occurs when a parallel beam of light from a He-Ne laser falls on two narrow slits 0.052 mm apart?

How can we calculate the spacing between fringes in the center of the pattern produced on a screen 4.1 m away?

The spacing of fringes in the center of the pattern on the screen 4.1 m away is 5 cm.

Young's double-slit interference occurs when a He-Ne laser beam falls on two closely spaced narrow slits, resulting in a pattern of dark and bright fringes on a screen.

To calculate the spacing between fringes at the center of the pattern, we use the formula y = λL/d, where λ is the laser's wavelength, L is the distance to the screen, and d is the separation between the slits.

Young's double-slit interference is an exciting phenomenon in the world of optics that allows us to explore the behavior of light waves. When a parallel beam of light from a He-Ne laser falls on two very narrow slits spaced 0.052 mm apart, a fascinating pattern of dark and bright fringes is produced on a screen some distance away.

To determine the spacing between these fringes at the center of the pattern on a screen 4.1 m away, we apply the principles of Young's double-slit interference. By using the formula y = λL/d, where λ is the laser's wavelength (633 nm), L is the distance to the screen (4.1 m), and d is the separation between the slits (0.052 mm converted to meters), we can calculate that the fringes are 5 cm apart.

This calculation showcases the intricate nature of light waves and how they interact when passing through narrow slits. Understanding Young's double-slit interference not only sheds light on the behavior of light but also opens up a world of possibilities in the study of optics and wave phenomena.
