In a Young's double slit experiment 15 fringes are observed on a small portion of the screen when light
of wavelength 500 nm is used. Ten fringes are observed on the same section of the screen when
another light source of wavelength λ is used Then the value of λ is (in nm)
    Correct answer is '750'. Can you explain this answer?

    Let's first use the formula for the number of fringes in a Young's double slit experiment:

    n = (Dλ) / d

    where n is the number of fringes, D is the distance from the slits to the screen, λ is the wavelength of light, and d is the distance between the slits.

    For the first light source with wavelength 500 nm, we have:

    n1 = (Dλ1) / d

    where n1 = 15 and λ1 = 500 nm.

    For the second light source with wavelength λ2, we have:

    n2 = (Dλ2) / d

    where n2 = 10.

    We want to find the ratio of the two wavelengths, so let's divide the two equations:

    n1/n2 = (Dλ1/d) / (Dλ2/d)

    Simplifying:

    n1/n2 = λ1 / λ2

    Substituting the given values:

    15/10 = 500 nm / λ2

    Solving for λ2:

    λ2 = (500 nm) * (10/15) = 333.33 nm

    Therefore, the ratio of the two wavelengths is:

    λ1 / λ2 = 500 nm / 333.33 nm = 1.5

    So the first wavelength is 1.5 times longer than the second wavelength.
