17.1 Understanding Diffraction and Interference
- No, the color is determined by frequency. The magnitude of the angle decreases.
- No, the color is determined by wavelength. The magnitude of the angle decreases.
- Yes, the color is determined by frequency. The magnitude of the angle increases.
- Yes, the color is determined by wavelength. The magnitude of the angle increases.
A double slit is located at a distance x from a screen, with the distance along the screen from the center given by y . When the distance d between the slits is relatively large, there will be numerous bright bands.
For small angles (where sinθ = θ, with θ in radians), what is the distance between fringes?
17.2 Applications of Diffraction, Interference, and Coherence
- All three interference pattern produce identical bands.
- A double slit produces the sharpest and most distinct bands.
- A single slit produces the sharpest and most distinct bands.
- The diffraction grating produces the sharpest and most distinct bands.
