Question:
The image is not seen. 2. In an experiment with Foucault's apparatus, the various distances used are as follows: Distance between the rotating and the fixed mirror $=16 \mathrm{~m}$ Distance between the lens and the rotating mirror $=6 \mathrm{~m}$, Distance between the source and the lens $=2 \mathrm{~m}$. When the mirror is rotated at a speed of 356 revolutions per second, the image shifts by $0.7 \mathrm{~mm}$. Calculate the speed of light from these data.
Solution:
