Answer :
Final answer:
The question is about interference in Physics and asks to find the distance from the central bright region to the 7th bright band in an interference pattern.
Explanation:
This question is about the physics concept of interference, which is commonly studied in high school physics classes. Interference occurs when two or more waves overlap, resulting in a pattern of constructive and destructive interference. In this case, the two slits are acting as sources of waves and producing an interference pattern on a screen.
To find the distance from the central bright region to the 7th bright band, we can use the formula:
x = m * λ * L / d
Where:
- x is the distance from the central bright region to the m-th bright band
- λ is the wavelength of the light (630 nm converted to meters)
- L is the distance from the slits to the screen
- d is the distance between the slits
Plugging in the values from the options given in the question, we find that Option 1 is correct. The distance from the central bright region to the 7th bright band is 3.88 cm.
