Answer:
Explanation:
The frequency of an electromagnetic wave is given by
where
is the speed of light
is the wavelength
For the light wave in this problem, the wavelength is
So by using the equation above, we find its frequency:
The frequency of light can be found by using the formula f = c ÷ λ, where c is the speed of light and λ is the wavelength. By substituting these values into the formula, you can calculate the frequency of light with a given wavelength.
When you are given the wavelength of light and asked to find its frequency, you would use the formula c = fλ, where c is the speed of light (3.00 x 10⁸ m/s in vacuum), f is the frequency, and λ is the wavelength. To find the frequency, we rearrange this formula to get f = c ÷ λ. Given the wavelength λ = 6.33 x 10^-7 m, we can substitute these values into the rearranged formula to find the frequency:
f = (3.00 x 10⁸ m/s) ÷ (6.33 x 10^-7 m)
By calculating the above equation, you will find the frequency of the light with the given wavelength.

The force that pushes electrons along in a circuit is called the electric field.
The force that pushes electrons along in a circuit is called the electric field. The electric field in a wire points from the higher potential end to the lower potential end and provides the force necessary to keep the electrons moving. The electrons, carrying a negative charge, move on average in the opposite direction of the electric field.

Explanation:
Answer: Option (C) is the correct answer.
Explanation:
Sodium has atomic number 11 and its electronic distribution is 2, 8, 1. Whereas chlorine has atomic number 17 and its electronic configuration is 2, 8, 7.
Therefore, we can see that sodium has one extra electron and chlorine has deficiency of one electron.
So, in order to complete their octet sodium will give its one valence electron to the chlorine atom. Hence, there is exchange of electrons and thus it will result in the formation of ionic bond.
Thus, we can conclude that in sodium chloride electron movement is related to the bonding as electrons exchange creating ions to form an ionic bond by electrostatic attraction.

Answer:
The revolution of the earth around the sun and the tilt of the earth's axis cause the changing of the seasons.
Explanation:
The Earth's rotation causes day and night, while its revolution causes seasons. This happens due to how the rotation exposes different parts of the Earth to the sun, and how the tilt of the Earth's axis during revolution causes varying sunlight exposure.
The rotation of Earth on its axis causes day and night. This astronomical phenomenon happens because as the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night. On the other hand, the revolution of the Earth around the sun causes the seasons. As the Earth orbits the Sun, the tilt of our planet's axis causes different parts of the Earth to receive varying degrees of sunlight throughout the year, which results in the changes in weather conditions we know as seasons.
