Two light emitting sources of wavelength 500 nm are separated by a distance 2.2 \(\times\) 10-2 cm. A detector can be moved on the line S1P which is perpendicular to S1S2 as shown in the figure below:
The minimum and maximum path difference at the detector as it is moved along the line S1P, are (respectively)
- zero, 2.2 \(\times\) 10-2cm
- zero, 1.1 \(\times\) 10-2cm
- zero, zero
- 2.2 \(\times\) 10-2cm, 2.2 \(\times\) 10-2cm
Answer
(A) zero, 2.2 10 -2 cm
