High School

Two slits separated by 0.030 mm are illuminated with green light (\( \lambda = 630 \) nm).

Choose the correct option for the distance from the central bright region to the 7th bright band:

A. 3.88 cm
B. 38.8 cm
C. 388 cm
D. 3880 cm

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.
