Which aspect of sound and light can easily be modeled with both particles and waves?
Sound has no particle properties, its wave properties include its ability to interfere with other sound waves and its ability to diffract.
Light is modelled as having particle-wave duality. Meaning it has some properties of being a particle and some of being a wave.
This was originally proposed by Einstein to explain the photoelectric effect, which won him the Nobel prize (note, he did not win one for the theory of relativity).
The photo electric effect is the phenomenon of electrons being released from a surface when electromagnetic radiation of a certain frequency is incident on it.
All materials have a property called the "work function", this is the amount of energy an electron from the outer shell of an atom needs to break loose.
Surfaces emit electrons only when the radiation surpasses a certain frequency, and after that, an higher frequency does not affect the number of electrons released, but affects the energy they have when released.
Intensity affects the number of electrons released, but not whether they are or not.
This is explained by the fact the light energy arrives in quantised packages called photons, and only if the photon has enough energy to release an electron will it do so, no matter how many are arriving each second.

What is the relationship between light mass and the behavior of particles in quantum physics?
In quantum physics, the behavior of particles is influenced by their mass and the presence of light. Light can affect the movement and properties of particles, leading to phenomena like wave-particle duality and quantum entanglement. The relationship between light, mass, and particle behavior is a key aspect of understanding the quantum world.
What particles do streams of light act like?
Streams of light can behave like both particles and waves. In some experiments, light exhibits particle-like behavior known as photons, while in other experiments it shows wave-like behavior such as interference and diffraction. This duality is a fundamental aspect of quantum mechanics.
When you shine a flashlight across a room you see the beam of light on the wall Why do you not see the beam of light in the air?
You see the beam of light on the wall because it scatters light particles, making them visible. In the air, the light particles are not as concentrated, so they are not as easily visible to the human eye. This phenomenon is known as Rayleigh scattering.
What is the explanation for the tyndal effect?
The Tyndall effect is the scattering of light by colloidal particles in a transparent medium, such as a liquid or a gas. When light passes through this medium, it interacts with the colloidal particles, causing the light to scatter and become visible. This effect is used to determine the presence of colloidal particles in a substance.
What microscopic specks of dust or smoke are moving around?
Those are most likely particles of dust or smoke that are reflecting light and appearing as tiny specks. Dust particles are commonly found in indoor air and can be easily visible when they catch light. Smoke particles can also be airborne and visible if there is smoke present in the environment.
Which can be modeled by light beaming from a lighthouse?
Ray

Why only lyophobic colloids show tyndall effect?
Lyophobic colloids have particles that repel the dispersion medium, preventing them from easily mixing. This causes the particles to scatter light, which is why they exhibit the Tyndall effect. In lyophilic colloids, the particles have an affinity for the dispersion medium and do not scatter light as effectively.

Can light waves be modeled as sound waves?
Yes, but not very well.
Particles of light are called what?
Light particles are called Photons.
Is Light has many of the properties of waves but light can also act as though it is a stream of?
... particles.... particles.... particles.... particles.
How can you tell the difference between a solution and a colloid?
a colloid contains larger particles than a solution. the particles are still too small to be seen easily, but are large enough to scatter a light beam
