In a young's double slit experiment, green light is incident on the two slits. The interference pattern is observed on a screen. Which of the following changes would cause the observed fringes to be more closely spaced?

In a Young's double-slit experiment, green light is incident on the two slits. The interference pattern is observed on a screen. Which one of the following changes would cause the observed fringes to be more closely spaced?

In Young's double slit experiment, if one of the slit is closed fully, then in the interference pattern

In Young's double slit experiment, if one of the slit is closed fully, then in the interference pattern

In Young's double slit experiment, the interference bright fringes are of:

In Young's double slit experiment, if the two slits are illuminated with separate sources, no interference pattern is observed because

In Young's double slit experiment, if the two slits are illuminated with separate sources, no interference pattern is observed because

If Young's double-slit experiment is performed under water, how would be observed interference pattern be affected ?
