Is a photon equivalent to a wavelength?
Each photon has a wavelength and a frequency. The wavelength is defined as the distance between two peaks of the electric field with the same vector. The frequency of a photon is defined as how many wavelengths a photon propagates each second.
How is the size of the photon related to light?
Very roughly, the interaction range of a photon scales with its wavelength, so light of longer wavelength is more likely to interact with a conductive material than light of a shorter wavelength. In this way you could say the “size” of photon is basically the width of its wavelength.
Are light waves and photons the same?
At the beginning of the twentieth century, the discovery that energy is quantized led to the revelation that light is not only a wave, but can also be described as a collection of particles known as photons. Photons carry discrete amounts of energy called quanta.
Do radio waves travel at the speed of light?
Radio waves travel like light waves. They transmit radio waves through space to antennas here on the ground.) Sound travels at approximately 1,100 feet per second (766 miles per hour). Radio waves travel at the speed of light, which is approximately 186,000 miles per second.
What is the photon energy of radio waves?
E=hf=hcλ(energy of a photon) E = h f = h c λ (energy of a photon) , where E is the energy of a single photon and c is the speed of light….Ionizing Radiation.

Are all photons the same?
All photons (if they carry the same energy within them) are identical to all other photons of that energy. Protons are identical to other protons, and neutrons are identical to other neutrons. All of these particles are distinguished from each other by their mass, electric charge, and a property called their spin.
Do photons vary in size?
where re is the classical radius of an electron. Since the length of a photon is equal to half of the wavelength and the radius is proportional to square root of the wavelength, the size and shape of a photon vary with the photon energy or wavelength.
Is photon smaller than an electron?
the size of photons and electrons are same as mass,but electron is negatively charged particle and photon is the energy (quanta).
What is the size of a photon?
A photon is in shape like a thin stick if its energy is lower than the rest energy of an electron and like a plate if its radius is smaller than the classical radius of an electron. For a photon of hν=13.6 eV, the photon radius is 34.9 pm and is less than the Bohr radius.
What is the relationship between waves and photons in light?
Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein’s light quantum theory is that light’s energy is related to its oscillation frequency.
Are radio waves and photons the same wave?
Light, radio waves and the aforementioned wave types are based upon the same electromagnetic wave, but each one occurs at different frequency ranges. The complete electromagnetic spectrum is found below. The photon is said to be in ‘quantum form’ because the electromagnetic wave is not a continuous wave.
How does vibration affect the wavelength of a photon?
A faster vibration causes a photon with a shorter wavelength and greater energy and a slower vibration causes a photon with a longer wavelength and lower energy. This results in the different types of waves seen in the electromagnetic spectrum (e.g. x-rays versus radio waves).
Why is radio frequency radiation described as a particle-like wave?
Radio-frequency radiation is described as particle-like because a single radio-frequency photon will show up as the energization of a single electron in some radio receptor. (It could be Eduard-Gabiel Munteanu is correct about the “size” of a photon.
What is the difference between high energy photons and low energy photons?
Low energy photons (such as radio photons) behave more like waves, while higher energy photons (such as X-rays) behave more like particles. The electromagnetic spectrum can be expressed in terms of energy, wavelength or frequency.
