The diagrams illustrate how the apparatus is set up for a Young’s slits experiment, together with part of the pattern produced on the screen, with a ruler shown beside it. What wavelength does the light have?
- A$4.8 \times 10^{-7}\,\text{m}$
- B$5.4 \times 10^{-7}\,\text{m}$
- C$3.2 \times 10^{-6}\,\text{m}$
- D$3.4 \times 10^{-6}\,\text{m}$
