JEE Mains · Physics · STD 12 - 10. Wave optics
In the Young's double slit experiment the intensity produced by each one of the individual slits is \(I_0\). The distance between two slits is 2 mm . The distance of screen from slits is 10 m . The wavelength of light is \(6000\) Å. The intensity of light on the screen in front of one of the slits is _________ .
- A \(2I_{0}\)
- B \(I_{0}\)
- C \(\frac{I_{0}}{2}\)
- D \(4I_{0}\)
Answer & Solution
Correct Answer
(B) \(I_{0}\)
Step-by-step Solution
Detailed explanation
\(d =2 mm\) \(D =10 m\) \(\lambda=6000 \)Å \(y=\frac{d}{2}(\) in front of one slit \()\) \(I=4 I_0 \cos ^2\left(\frac{2 \pi}{\lambda} \cdot \frac{y}{D} d\right)\) \(\Rightarrow I = I _0\)
