Question

question 9 of 10
the idea that light can act as packets led to what new field of science?
a. quantum mechanics
b. nuclear mechanics
c. electrical mechanics
d. physical mechanics

Explanation:

The concept of light acting as packets (photons) is a fundamental idea in quantum mechanics. Nuclear mechanics is not a standard field related to light as packets. Electrical mechanics focuses on electrical systems, and physical mechanics is a broader, less specific term not tied to this quantum - related concept of light. So the correct option is A.

Answer:

A. Quantum mechanics
