The color of light that will be diffracted at a greater angle from a diffracting grating is THE YELLOW COLOR.
This is because, the degree of diffraction depend on the wavelength of light and light color with shorter wavelength are diffracted at a larger angle than those with longer wavelengths. The wavelength of the yellow color is much more smaller than that of the red color.
<h3>
<u>ANSWER</u></h3>
2. Neon, only
<h3>
<u>EXPLANATION</u></h3>
When Na and F combine they form an electron configuration of 2-8. Na electron configuration is 2-8-1 while F is 2-7, so when they form an ionic bond F will gain Na outermost electron to complete its valence shell due to having a higher negativity. Neon has an electron configuration of 2-8 but argon has 2-8-8.
Answer: -
C) because the moon rotates once on its axis in the same time that it takes to revolve around the earth
Explanation: -
The moon rotates about it's axis one full time at about the same time as it takes to rotate around the earth.
This leads to only one side of the moon always appearing to Earth, called the near side.
One side of the moon is always not seen from the earth. It is called the far side of the moon.
Thus we can never see the far side of the moon because the moon rotates once on its axis in the same time that it takes to revolve around the earth
