Light can behave as a particle and a wave at the same time. An example of light acting as both a particle and a wave is the digital camera---the lens refracts (bends and focuses) waves of light that hit a charge-coupled device (CCD). The photons kick electrons out of the silicon in the CCD. The electrons are detected by electronics that interpret the number of electrons released and their position of release from the silicon to create an image. Another example is when you observe the build-up of the alternating light and dark pattern from diffraction (a wave phenomenon) from light passing through a narrow slit. You see one bright spot (a photon), then another bright spot (another photon), then another... until the diffraction pattern is created from all of the accumulated photons. This happens so quickly that it is undetectable to the human eye.

The smallest particle of oxygen that behaves like oxygen is an oxygen what?
The smallest particle of oxygen that behaves like oxygen is an oxygen molecule, which consists of two oxygen atoms bonded together.
What are examples of substances that do not follow the particle model?
Examples of substances that do not follow the particle model include light and electromagnetic radiation. These entities exhibit wave-like behavior and are not composed of particles in the same way as matter.
The smallest particle of oxygen that behaves like oxygen is an oxygen?
The smallest particle of oxygen that behaves like oxygen is the oxygen molecule, which consists of two oxygen atoms bonded together. Each oxygen atom in the molecule retains its chemical properties and reactivity, making the molecule as a whole still function as oxygen.
What does the dual nature of electrons mean?
The dual nature of electrons refers to their ability to exhibit both wave-like and particle-like behavior. This duality is described by quantum mechanics, where electrons can behave as discrete particles with localized positions, or as waves with properties such as interference and diffraction. This phenomenon is a fundamental aspect of the behavior of subatomic particles.
How are the motions of an alpha particle and a gamma ray affected when each passes between a positively charged electrode and a negatively charged electrode?
The alpha particle is actually a helium-4 (4He++) nucleus, and it's composed of two protons and two neutrons. This gives it an overall positive charge. When directed between the electrodes as asked, its positive charge will cause it to be attracted by the negative electrode and repelled by the positive electrode. It's simple electrostatics with opposite charges attracting and like charges repelling. The gamma ray is high energy electromagnetic radiation. It will pass between the electrodes and be unaffected.
What are the problems with the particle theory?
Electromagnetic radiation sometimes behaves like waves - for example, interference.
How can light be defined in simplest form?
The common definition of 'light' (visible) is electromagnetic radiation visible to the human eye. It is only a small part of what is known as the 'electromagnetic spectrum' - which is the range of wavelengths of all possible electromagnetic radiation. Light is electromagnetic radiation, as reported. But, even though it behaves like a wave, it also behaves as a particle. We can call a particle of light a photon. Light has two identities, a "duality" of sorts, that is called wave-particle duality. That's about as simple as it can get. Light is called a "wavicle" by some, and for reason that it displays qualities of both a wave and a particle.
What radioactive emission is a particle?
Alpha emission is a 4helium nucleus, which behaves like a particle. Beta emission is an electron, which behaves like a particle. Gamma emission is a photon, which behaves like a particle. Experiments can also be set up to show their wavelike properties (for alpha, beta, and gamma radiation).
How is EMR classified as both a wave and a particle?
EMR (electromagnetic radiation) is classified as both a wave and a particle because of its dual nature as described by quantum mechanics. In some experiments, EMR behaves like a wave with characteristics such as interference and diffraction, while in others, it behaves like a particle called a photon with characteristics like discrete energy levels. This behavior is known as wave-particle duality.
What is the smallest amount of energy that can be emitted or absorbed as electromagnetic radiation?
The smallest amount of energy that can be emitted or absorbed as electromagnetic radiation is a photon, which behaves like a particle carrying discrete energy. This minimum amount of energy is determined by the frequency of the radiation, according to Planck's equation E=hf, where E is energy, h is Planck's constant, and f is frequency.
What is a photon-?
A particle of light. Or, in general, of an electromagnetic wave.
What is the name for a particle of em radiation?
Photon - you can think of it as a bundle of waves
What is electromagnetic radiation emitted tiny packets called?
Electromagnetic radiation emitted in tiny packets is called photons. Photons are the fundamental particles that make up electromagnetic radiation. They have both wave-like and particle-like properties.
What are the characteristics of light?
Light is a form of electromagnetic radiation that travels in waves and behaves like both a particle and a wave. It can be reflected, refracted, absorbed, and transmitted. Light has properties such as intensity, frequency, wavelength, and speed. It can also be polarized and exhibit interference and diffraction.
When light behaves like a particle what is the particle called?
When light behaves like a particle, it is called a photon. Photons are the fundamental particles of light and carry energy and momentum.
Is light made of matter?
Light is energy, and energy is not matter.
What is meat by dual nature of radiation?
The dual nature of radiation refers to the fact that electromagnetic radiation, like light, exhibits both wave-like and particle-like properties. This duality is described by quantum mechanics, where radiation can behave as waves in some experiments (wave-particle duality) and as particles (photons) in others.
