Question

question 3 of 10
the idea that light can act as packets led to what new field of science?

a. physical mechanics

b. quantum mechanics

c. electrical mechanics

d. nuclear mechanics

Explanation:

• Physical mechanics: Deals with the motion of macroscopic objects under forces, not related to light as packets.
• Quantum mechanics: Explains phenomena at the atomic and sub - atomic level. The concept of light acting as packets (photons) is a fundamental part of quantum mechanics.
• Electrical mechanics: Focuses on electrical circuits and electrical - mechanical systems, not relevant to light as packets.
• Nuclear mechanics: Concerned with the nucleus of an atom, not with the nature of light as packets.

Answer:

B. Quantum mechanics
