The wave-particle duality of light refers to the fact that light exhibits characteristics of both waves and particles, which seems paradoxical based on our everyday experiences with matter. This concept is a fundamental aspect of quantum mechanics and has been widely studied and accepted in physics.
To understand this paradox, let's first consider the wave nature of light. Light is an electromagnetic wave that propagates through space. Like any wave, light exhibits properties such as interference, diffraction, and polarization. These characteristics are best described by wave models, like the famous double-slit experiment.
In the double-slit experiment, a beam of light is passed through two narrow slits and then projected onto a screen. When only one slit is open, the light passes through that slit and appears as a single stripe on the screen behind it. However, when both slits are open, instead of seeing two stripes, an interference pattern of alternating light and dark fringes is observed. This phenomenon can only be explained if we consider light as a wave, as the pattern arises due to the interference of the light waves passing through the slits.
On the other hand, the particle nature of light is evident in phenomena like the photoelectric effect and the Compton effect. The photoelectric effect occurs when light interacts with matter, causing the ejection of electrons. This effect cannot be explained by considering light as a classical wave but is better described using the particle nature of light, treating it as a stream of photons (particle-like packets of energy). Similarly, the Compton effect demonstrates that light can collide with particles, transferring momentum as if it were composed of particles.
This duality often leads to the "wave-particle paradox" when trying to comprehend the complete nature of light. It seems counterintuitive that light can simultaneously behave as both a wave and a particle.
Quantum mechanics attempts to reconcile this paradox by suggesting that particles, including photons, have both wave-like and particle-like qualities. The wave-particle duality is not a contradiction but rather a fundamental aspect of nature that defies classical intuition.
Here's a diagram to help visualize the wave-particle duality of light:
```
Wave-like behavior | Particle-like behavior
--------------------------------------------------------------------------------
Interference | Photoelectric Effect
Diffraction | Compton effect
Polarization | Absorption/Emission Spectra
Double-slit experiment | Photon Detection
```
In conclusion, the wave-particle paradox of light represents the coexistence of particle-like and wave-like behaviors in the nature of light. Although contradictory from a classical perspective, this paradox is consistent with the principles of quantum mechanics. The study of this paradox has led to breakthroughs in understanding the fundamental nature of light and laid the foundation for the development of quantum theory.

To calculate Tamala's displacement, we need to find the straight-line distance and direction from her starting point to her final position. We can use the Pythagorean theorem to find the magnitude (distance) of the displacement and trigonometry to determine its direction.
First, let's break down Tamala's movements:
- She goes 35 meters east.
- Then, she goes 20 meters north.
- Next, she moves 12 meters west.
- After that, she goes 6 meters south.
- Finally, she moves another 11 meters west.
To find the horizontal and vertical components of her displacement, we can sum up the distances traveled east-west and north-south separately:
Horizontal displacement = 35 m east - 12 m west - 11 m west = 35 m - 23 m = 12 m west
Vertical displacement = 20 m north - 6 m south = 20 m - 6 m = 14 m north
Now, we can use these components to calculate the straight-line distance (displacement) using the Pythagorean theorem:
Displacement = sqrt((Horizontal displacement)^2 + (Vertical displacement)^2)
Displacement = sqrt((12 m)^2 + (14 m)^2)
Displacement = sqrt(144 m^2 + 196 m^2)
Displacement = sqrt(340 m^2)
Displacement = 18.44 m (approximately)
Therefore, Tamala's displacement is approximately 18.44 meters.
To determine the direction of the displacement, we can use trigonometry. The direction can be found by taking the inverse tangent (arctan) of the vertical displacement divided by the horizontal displacement:
Direction = arctan(Vertical displacement / Horizontal displacement)
Direction = arctan(14 m / 12 m)
Direction = arctan(1.17)
Direction = 49.4 degrees (approximately)
Thus, Tamala's displacement is approximately 18.44 meters in a direction of 49.4 degrees (measured counterclockwise from east).
