The modern view of an electron orbital in an atom can best be described as Question 10 options:

A)

a three-dimensional space that shows the probability where an electron is most likely to be found.

B)

an elliptical path an electron follows around the nucleus.

C)

a spherical shell on the surface of which an electron can be found.

D)

a circular path an electron follows around the nucleus.

Part(a): The frequency is .

Part(b): The speed of the wave is .

Explanation:

Given:

The distance between the crests of the wave, .

The time required for the wave to laps against the pier,

The distance between any two crests of a wave is known as the wavelength of the wave. So the wavelength of the wave is .

Also, the time required for the wave for each laps is the time period of oscillation and it is given by .

Part(a):

The relation between the frequency and time period is given by

Substituting the value of in equation (1), we have

Part(b):

The relation between the velocity of a wave to its frequency is given by

Substituting the value of and in equation (2), we have
