In a double-slit interference pattern the path length from one slit to the first bright fringe of a double-slit interference pattern is longer than the path length from the other slit to the fringe by:A. one-quarter of a wavelength. B.one-half of a wavelength. C.one full wavelength. D.three-quarters of a wavelength. E.two full wavelengths

C.one full wavelength.

Explanation:

In a double-slit experiment, the figure projected on the distant screen shows alternating bright fringes (constructive interference) and dark fringes (destructive interference).

The conditions for the two types of interference are the following:

- Constructive interference (bright fringe) occurs when the path length difference between the two slits is an integer multiple of the wavelength, so when

where are the path length from the two slits, n is an integer, and is the wavelength.

- Destructive interference (dark fringe) occurs when the path length difference between the two slits is an odd multiple of half-wavelength, so when

where n is an integer.

Here we want to know what happens at the first bright fringe (next to the central bright fringe). Since it is a bright fringe, the path difference must be an integer multiple of the wavelength. Moreover, the central maximum is the one having

n = 0

Therefore, the first bright fringe next to it will be the one having

n = 1

This means that the correct answer is

C.one full wavelength.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
