| a. | The angular separation of the fringes increases if the screen is moved towards the plane of the slits. |
| b. | The angular separation of the fringes increases if the (monochromatic) source is replaced by another (monochromatic) source of a shorter wavelength. |
| c. | The angular separation of the fringes increases if the separation between the two slits is increased. |
| d. | The sharpness of the fringes increases when the source slit is moved closer to the double-slit plane. |
