Question

In a Young's double-slit experiment, the distance between the slits is \( 0.2 \, \text{mm} \) and the distance between the screen and the slits is \( 2 \, \text{m} \). If the wavelength of the light used is \( 600 \, \text{nm} \), calculate the distance between the two adjacent bright fringes.

• A. \( 0.3 \, \text{mm} \)
• B. \( 0.6 \, \text{mm} \)
• C. \( 1.2 \, \text{mm} \)
• D. \( 1.5 \, \text{mm} \)

Hint:

Remember: The fringe width in a Young's double-slit experiment depends on the wavelength of light, the distance between the slits, and the distance to the screen. The larger the distance \( L \), the larger the fringe width.
