Question: In a double-slit experiment, if the wavelength of light is increased, what happens to the distance between the fringes?

Options:

Correct Answer: Increases

Solution:

The distance between the fringes increases with an increase in wavelength, as fringe separation is directly proportional to wavelength.

In a double-slit experiment, if the wavelength of light is increased, what happens to the distance between the fringes?

In a double-slit experiment, if the wavelength of light is increased, what happens to the distance between the fringes?

Step 1: Understand what a double-slit experiment is. It involves shining light through two narrow slits to create a pattern of light and dark stripes called fringes.
Step 2: Know that the wavelength of light is the distance between two peaks of the light wave.
Step 3: Realize that the distance between the fringes (fringe separation) is affected by the wavelength of the light used.
Step 4: Remember that if the wavelength increases, the distance between the fringes also increases.
Step 5: Conclude that the relationship between wavelength and fringe separation is direct; as one goes up, so does the other.

Double-Slit Experiment – A demonstration of the wave nature of light, showing interference patterns created by overlapping waves from two slits.
Fringe Separation – The distance between consecutive bright or dark fringes in an interference pattern, which is influenced by the wavelength of light used.
Wavelength and Interference – The relationship between the wavelength of light and the resulting interference pattern, where longer wavelengths result in wider fringe separation.
