question 29

Multiple Choice

In a Young's double-slit experiment, the separation between slits is d and the screen is a distance D from the slits.D is much greater than d and $\lambda$ is the wavelength of the light.The number of bright fringes per unit length on the screen is:

• A)"Dd/\(\lambda\)"
• B)"D\(\lambda\)/d"
• C)"D/d\(\lambda\)"
• D)"\(\lambda\)/Dd"
• E)"d/D\(\lambda\)"
