what principle is responsible for alternating light and dark bands when light passes through two or more narrow slits?
olya-2409 [2.1K]

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.

A drone is flying horizontally when it runs out of power and begins to free fall from 16 m. No drag. If it lands 40 m away (in t
marysya [2.9K]

Answer:

the horizontal velocity while it was falling is 22.1 m/s.

Explanation:

Given;

height of fall, h = 16 m

horizontal distance, x = 40 m

The time to travel 16 m is calculated as;

t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 16}{9.8} } \\\\t = 1.81 \ s

The horizontal velocity is calculated as;

v_x = \frac{X}{t} \\\\v_x = \frac{40}{1.81} \\\\v_x = 22.1 \ m/s

Therefore, the horizontal velocity while it was falling is 22.1 m/s.

your friend want to know the amont of salt added to her favorite fast food french fries what would you recommend that she do to
Alexeev081 [22]
That nutritional information is usually not posted up on the wall,
but by federal law, it's available on request, to any customer, at
any fast-food place. 

All she has to do is ask to see the manager, and then ask the
manager for the nutritional information booklet. 

She'll get a nice printed booklet that tells the salt content in the
fries, AND the amount of many other substances in ALL the items
sold at that place.

It's the law.  Don't be bashful.
