Does light need particles to move?
Light is the visible form of electromagnetic radiation. All the forms of electromagnetic radiation travel at the speed of light, when they are traveling through a vacuum. A vacuum is a space which contains no particles. The space between the sun and the earth is mostly empty space. When light makes contact with a particle, the light interacts with the atoms of the particle. In chemistry, we learn how electrons interact with light. Visible light is composed of many colors. Each color has a specific frequency. Energy = Plank's constant * frequency This means each color of light has a specific amount of energy. Before the electrons absorbed the energy, the electrons are in their "ground" state. This is their most stable state. When electrons absorb a specific amount of energy, we say that the electrons are in their "excited" state. This is an unstable state. To become stable energy is released, and we see a specific light of a specific color. When you see a blue shirt, you are seeing the result of electrons releasing a specific amount of electromagnetic energy, in the form of blue light. What happened to the other colors in the visible light? The atoms absorb the rest of the energy. This causes the atoms to vibrate at a higher frequency. Now the atoms have more kinetic energy. Temperature measures the average kinetic energy of the atoms. So the temperature of the shirt is increasing. When sun light shines on a blue shirt, the temperature of the shirt increases. You may be wondering what all this has to do with your question! The energy of electron is called orbital energy. The energy of the vibrating atom is called kinetic energy. The light's energy was converted into orbital energy and kinetic energy. During this time, the light does not exist. When the blue light is emitted from the atoms, light does exist. During this process, the form of a specific amount of the energy is changing from white light to orbital energy to blue light. The rest of the energy is in the form of vibrational kinetic energy of the atoms. This form of energy is actually what we call heat energy. Average velocity = distance ÷ time Since the light did not exist for a specific amount of time, but the clock kept on ticking, the average velocity of the light is less than the speed of light in a vacuum. Light does not need particles to travel. But the particles need the energy of the light to be seen by us and to experience some heat energy.
How energy travels without particles?
Energy can travel through space in the form of electromagnetic waves, such as light and radio waves. These waves don't require particles to propagate because they are made up of oscillating electric and magnetic fields. This allows energy to be transferred over long distances without the need for a physical medium.
Does the particles need to contain kinetic energy for osmosis and diffusion?
Yes, particles need to contain kinetic energy in order for osmosis and diffusion to occur. This kinetic energy allows the particles to move and spread out from an area of high concentration to an area of low concentration through the process of osmosis and diffusion.
Does light need a substance to travel through?
No. It is radiation, not vibration. As electromagnetic energy, it can travel through a vacuum, and only through transparent or translucent material.
What kind of microscope do you need to see particles?
To see particles, such as individual cells or microorganisms, you would typically need a light microscope. However, to see smaller particles like viruses or nanoparticles, you would need an electron microscope.
What is the minimum amount of energy that particles need to react when colliding is called the energy?
This energy is the activation energy.

What a cell need to transport particles by active transport?
Energy
Why do you need light in photosynthesis?
We need light in photosynthesis as Light provides the energy source. The process is based on light. The plants use light to convert energy. The same reason that we need air to breath.
Why do particles need to energy to evaporate?
Particles need energy to evaporate because evaporation involves overcoming intermolecular forces that hold them together in a liquid state. When a particle gains enough kinetic energy—often from thermal energy—it can break free from these forces and transition into the gaseous phase. This energy allows the particles to escape from the liquid surface, leading to evaporation. Essentially, without sufficient energy, particles remain bound in the liquid.
Does the particles need to contain kinetic energy for osmosis and diffusion?
Yes, particles need to contain kinetic energy in order for osmosis and diffusion to occur. This kinetic energy allows the particles to move and spread out from an area of high concentration to an area of low concentration through the process of osmosis and diffusion.
Where does a firefly get the energy to light up?
Animals get all the energy they need from the food they eat.
Does light need a substance to travel through?
No. It is radiation, not vibration. As electromagnetic energy, it can travel through a vacuum, and only through transparent or translucent material.
Do plants need light to mature?
Yes, plants need light to mature because light is essential for photosynthesis, the process by which plants convert light energy into chemical energy to produce food. Without sufficient light, plants cannot produce the energy they need to grow and develop properly.
Can a wind produce energy on its own?
Wind energy can provide all the energy that we need
What does light provide plants with?
Light provides plants with the energy they need to carry out photosynthesis. During photosynthesis, plants convert light energy into chemical energy, which is used to produce glucose, a simple sugar that serves as their primary source of food and energy. Additionally, light plays a key role in regulating various plant processes, such as growth, flowering, and fruit development.
