Question

Relate a real life phenomenon with each branch of physics
1 heat
2 light optics
3 sound
4 atomic physics
5 plasma physics

Answer 1

Real life phenomenon relating to above mentioned classification of physics   can be easily explained by taking the case of our star Sun

1)Sun produces heat energy, and it is one that we can feel here on earth and it is this heat which sustains life on earth.
2)After a rain we can see rainbow in sky ,it is because of light optics ,that is scattering of sun’s white light into seven different colors by water droplets present in the atmosphere after a rain.

3)luckly for us ,there is no atmosphere in outer space ,if there had one ,all the violent explotions happening in sun might have produced  big sound waves which would have destroyed earths life forms .
so taking example from earth itself ,just think of us humans ,we produce sound by our vocal cords by it’s vibrations and similarly we hear these sounds ,when these sounds vibrate our ear drum.

4)Again going back to sun ,the sustenance of sun is by atomic fusion where hydrogen atoms are combined to form helium atoms and this produces light and heat which I explained in 1st and 2nd examples.

5)and for plasma ,it is the forth state of matter and it is in this state of matter that our sun exist.
