The superposition principle is responsible for alternating light and dark bands when light passes through two or more narrow slits.
The intensity pattern that appears on the lit screen is determined by the superposition principle. When the difference in pathways from the two slits to a location on the screen equals an integral number of wavelengths (0,λ,2λ ,...), constructive interference takes place.
The fact that the two waves' crests follow different paths ensures that they do. A distinctive pattern of brilliant and dark fringes is seen when monochromatic light illuminates a distant screen after passing through two small openings. The superposition of overlapping light waves coming from the two slits results in this interference pattern.

She does work from the moment she touches the book until she lets it go. Work is anything that requires energy. Therefore, she is working as she picks up the book, carries it, and when she is lifting it onto the shelf.
Answer:
= 2.49 × 10³J
Explanation:
Total rotational kinetic energy K = nRT
R = 8.134 J/mol.K
n = 1 mol
T = 300 K
K = 1 × 8.314 × 300
= 2.49 × 10³J
