Answer 1

$\large\colorbox{red}{Answer}$

• Quantum mechanics is the branch of physics relating to the very small. it's the fundamental theory of physics which provides ba description of the physical properties of nature at the scale of atoms .
• umm ur second question is quite confusing. But as per as my knowledge says the speed of darkness is not yet discovered. Scientists are still working on it.
• I think the film of earlier cameras were made of paper.

Answer 2

✰ HeY Mate, here is your ANSWER,

⠀⠀⠀━━━━━━━━━━━━━━━━━━⠀⠀⠀

❍ Required Answer (1) :

➠ Definition of Quantum mechanics :

• ➥ In 1920's classical mechanics was replaced by Quantum mechanics. The word : (Quantum) means the smallest possible amount of something.

• ➥ Quantum Mechanics is now acknowledged as the correct understanding of all kinds of motion.

⠀⠀⠀━━━━━━━━━━━━━━━━━━⠀⠀⠀

❍ Explore More About It :

➲ Need of Quantum mechanics :

• We need it when dealing with very small things.

• We need it for understanding objects that is still smaller or when there are many atoms.

➪ Founders of Quantum mechanics :

• Niels Bohr and Max Planck, they are the founders of Quantum mechanics or theory, also each of them received a Nobel Prize in Physics .

⠀⠀⠀━━━━━━━━━━━━━━━━━━⠀⠀⠀

❍ Required Answer (2) :

➠ Speed of Darkness :

• Darkness travels at the same speed as light.

➣ So, the speed of darkness is ,

• Speed of Darkness = 3 × 10⁸ m/s. ✰

❍ Required Answer (3) :

➠ Film of earlier cameras were made of :

• The film of earlier cameras were made of celluloid.

➯ So, the answer = Celluloid.
