meriva

Answer:

please see the answer below

Explanation:

we can use the following expression:

\lambda=\frac{2nd}{m}

where lambda is the wavelength of the light, n is the refractive index of the film, d is the thickens of the film and m is the order of the diffraction pattern. If m=1, we obtain the max value of lambda for the colors that are reflected.

Hence, we have:

\lambda=\frac{2(1.333)(183nm)}{1}=487.878nm

for m=1 487.878nm is the more reflected light. Hence, all colors with wavelength below this values are not reflected.

the following are colors that are not reflected

- 780nm red

- 622nm orange

- 597nm yellow

- 577nm greeen

- 492nm blue

hope this helps!

Plastic and glass rods that have been charged by rubbing with wool and silk, respectively, hang by threads.
nikitadnepr [17]

Answer:

a. The object will attract the glass rod.

b. The object will repel the glass rod.

Explanation:

a. When you rub a plastic rod with wool, it becomes negatively charged. This is because the wool material loses some of its electrons to the plastic rod. The wool becomes positively charged while the plastic rod becomes negatively charged.

Hence, for an object to repel the negatively charged plastic rod, it must also be negatively charged. This is because objects with like charges repel one another.

On the other hand, when you rub a glass rod with a silk material, it becomes positively charged. This is because the glass rod loses its electrons to the silk material. The silk material then becomes negatively charged, while the glass rod becomes positively charged.

Therefore, the negatively charged object will attract the already positively charged glass rod.

b. For an object to attract a negatively charged plastic rod, then it must be positively charged, since unlike charges attract.

So, a positively charged object will repel the negatively charged glass rod.
