Question

In Young's double slit experiment with a source of light of wavelength 5860 Å, the first maxima will occur when ____________.

Options

• path difference is 9480 Å

• phase difference is 2`pi` radian

• path difference is 5860 Å

• phase difference is `pi` radian

Answer 1

In Young's double slit experiment with a source of light of wavelength 5860 Å, the first maxima will occur when path difference is 5860 Å.

Explanation:

`"For maxima, path difference," Deltal = "n" lambda`

`therefore "n" = 1, Deltal = lambda = 5860  Å`
