In young's double slit experiment,the two slits act as coherent sourcesof equal amplitude a and of wavelength 'lamda'.In another experiment with same setup the two slits are sources of equal amplitude and wavelength 'lamda',but are incoherent,.The ratio of intensity of light at the mid-point of the screeen in the first case to that of second case is?
Verified Answer
In young's double slit experiment,the two slits act as coherent source...
I coherent = n^2 * Io = 2^2 * Io = 4 Io
I incoherent = Io + Io = 2 Io
Hence ratio = 4/2 = 2/1

In young's double slit experiment,the two slits act as coherent source...
Explanation:
Coherent Sources:
- In Young's double slit experiment with coherent sources, the two slits act as coherent sources of equal amplitude a and wavelength λ.
- When coherent sources are used, the waves from the two slits interfere constructively and destructively, resulting in an interference pattern on the screen.
- The intensity of light at the mid-point of the screen is maximum due to constructive interference.
Incoherent Sources:
- In the experiment with incoherent sources, the two slits are sources of equal amplitude and wavelength λ, but are incoherent.
- Incoherent sources do not maintain a constant phase relationship, leading to random interference patterns on the screen.
- The intensity of light at the mid-point of the screen is reduced compared to the coherent case due to the lack of consistent constructive interference.
Ratio of Intensity:
- The ratio of intensity of light at the mid-point of the screen in the first case (coherent sources) to that of the second case (incoherent sources) can be calculated using the formula for intensity in interference patterns.
- The intensity ratio will be higher in the case of coherent sources compared to incoherent sources, as coherent sources produce a more defined interference pattern with higher intensity at the mid-point of the screen.
This difference in intensity between coherent and incoherent sources highlights the importance of maintaining a constant phase relationship between the sources to observe clear interference patterns in experiments like Young's double slit experiment.
