Why is the fireworks so gorgeous?

Fireworks have splendid colors including yellow, orange, green, blue, purple due to the glowing process of metal salts inside it.

How beautiful fireworks are

According to Earth Sky, in chemistry, salt is an ionic compound formed from the reaction between acids and bases. Electrically neutral salt molecules include positive ions and negative ions. For example salt (NaCl) includes positive ions (Na +) and negative ions (Cl-).

The most common metal used in fireworks is strontium carbonate (red fireworks), calcium chloride (orange fireworks), sodium nitrate (yellow fireworks), barium chloride (green fireworks) and copper chloride (blue fireworks). Purple fireworks often combine a combination of strontium (red) and copper (blue).

Metal salts are inserted into a big piece of a plum inside fireworks called "stars". Launchers and launchers push the fireworks high before exploding. In the process, a slow-burning fuse enters the fireworks core causing it to explode, igniting the star containing metal salts.

The heat from the partial combustion process is absorbed by metal atoms. Electrons surround the low orbit of excited atomic nuclei and jump to higher energy levels. When the heat dissipates, electrons return to a lower energy level or ground state, and release excess energy in the form of light .

Light travels in wave form. Different metal atoms that produce light with different colors are different when stimulated, because the light they produce moves at different wavelengths .

When metal salts emit light of visible short wavelengths, between 400 and 500 nanometers, they produce purple and blue. Longer wavelengths of light (in the range of 600-700 nm) produce orange and red colors. The average wavelength (500-600 nm) along the electromagnetic spectrum produces yellow and green.
