In a Young's double-slit experiment, the two slits behave as coherent sources. When coherent light waves superpose over each other they create an interference pattern of successive bright and dark regions due to constructive and destructive interference. Two slits $2\text{ mm}$ apart are illuminated by a source of monochromatic light and the interference pattern is observed on a screen $5.0\text{ m}$ away from the slits as shown in the figure. (i) What property of light does this interference experiment demonstrate ? (A) Wave nature of light (B) Particle nature of light (C) Transverse nature of light (D) Both wave nature and transverse nature of light
