All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
Blue
Because the color is due to the sodium. All of them have sodium, all of them give the same color. Technically nitrogen, oxygen, and chlorine have spectral lines as well; it's just that sodium's are much more prominent.
Pink
Sodium chloride (salt) gives a yellow-orange flame result.
It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
The yellow color of the flame is due only to sodium.
Blue
green
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/

Flame tests are often used to identify metals and other substances, such as sodium. If you expose the element sodium to flame, it will give off a bright, vibrant yellow color.
None. Using flame spectral analysis, we can use a prism or other device to determine the color of various metals. Nitrate gives no color. The purpose of the test is to give metal detection, qualitatively. Testing for nitrate is another test, not involving flame.
None.

There would be electron transitions in sodium atoms while the flame test. The majority of them would emit photons which would have same energy and frequency corresponding to yellow color.
