Select the correct answer.

Two sources of light of wavelength 710 nm are 9 m away from a pinhole of diameter 1 mm. How far apart must the sources be for th

Zepler [3.9K]

Answer:

7.8 mm

Explanation:

Wavelength = λ = 710 nm = 710×10⁻⁹ m

Distance between light sources = L = 9 m

Diameter of pinhole = d = 1 mm = 1×10⁻³ m

Rayleigh Criterion

$D=1.22\frac{L\lambda}{d}\\\Rightarrow D=1.22\frac{9\times 710\times 10^{-9}}{1\times 10^{-3}}\\\Rightarrow D=0.0077\ m=7.8\ mm$

Distance between difraction pattern is 7.8 mm.

The answers to your questions are as written below:

The objects that represents a negatively charged particle is : Image B
The object that represents a positively charged molecule is : Image A
The object that represents an uncharged molecule is : Image C
The object the will not move when in an electric fied is : Image C

<h3>Different types of charges molecules</h3>

A negatively charged molecule move inwards when placed in an electric field while positively charged molecule placed in a electric field will move outwards the electric field.

A neutral/uncharged molecule will remains still when placd in an elctric field due to the absence of charges.

Hence we can concude that the answers to your questions are as listed above.
