Homework Statement
Light propagates as waves, but exchanges energy as particles
Homework Equations
I don't understand the second part, i.e., light exchanges energy as particle. I need the help of members in this regard

The dual nature of light refers to the fact that light exhibits both wave-like and particle-like properties. This means that light can behave as both a wave and a stream of particles, depending on the experiment being conducted.
This phenomenon is known as wave-particle duality, which is a fundamental principle of quantum mechanics. It suggests that all particles, including light, have both wave-like and particle-like properties. The behavior of light is determined by the experimental setup and the observation of light.
The most famous experiment that demonstrates the dual nature of light is the double-slit experiment. This experiment shows that light can behave like a wave and interfere with itself, creating an interference pattern. Another experiment is the photoelectric effect, which shows that light can also behave as particles, transferring energy to electrons.
The dual nature of light is important because it helps us understand the behavior of light and other particles at a quantum level. It also plays a crucial role in modern technologies, such as lasers, fiber optics, and solar panels. Without an understanding of the dual nature of light, many of these technologies would not be possible.
The dual nature of light challenges our traditional understanding of the universe and the behavior of matter. It suggests that the universe is much more complex and mysterious than we previously thought and has led to the development of new theories and concepts in physics. It also raises questions about the nature of reality and the relationship between the observer and the observed.
