Correct answer choice is :

B) Red, orange, yellow, green, blue, indigo, and violet

Explanation:

A spectral color is a color that is extracted in a natural human by a single wavelength of light in the apparent rainbow, or by a comparatively narrow band of wavelengths, also recognized as monochromatic light. The combination of colors provided when the light is separated by a prism. Spectrum an indexed order of the elements of an radiation or wave. Electromagnetic rainbow the complete wavelength spectrum of electromagnetic waves.

The correct answer to this question is- B) Red, orange, yellow, green, blue, indigo, and violet.

EXPLANATION:

The visible region of the electromagnetic spectrum consists of white light with its constituent seven colors.

The constituent colors are known as violet, indigo, blue, green, yellow, orange and red respectively.

As per electromagnetic spectrum, these colors of light lie in the wavelength region ranging from 350 nm to 700 nm.

The wavelength of violet light is minimum, and is maximum for red light.

If we arrange these seven colors in the descending order of their wavelength, then they are arranged as follows-

Red > Orange > Yellow > Green > Blue > Indigo > Violet.

Hence, the perfect order is option B .

After a great many contacts with the charged ball, how is the charge on the rod arranged (when the charged ball is far away)?

faust18 [17]

Answer: Option (b) is the correct answer.

Explanation:

Since, there is a negative charge present on the ball and a positive charge present on the rod. So, when the negatively charged metal ball will come in contact with the rod then positive charges from rod get conducted towards the metal ball.

Hence, the rod gets neutralized. But towards the metal ball there is a continuous supply of negative charges. Therefore, after the neutralization of positive charge from the rod there will be flow of negative charges from the metal ball towards the rod.

Thus, we can conclude that negative charge spread evenly on both ends.
