How do you calculate the frequency of light emitted in chemicals?
There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).
What particle is emitted when Na-20 decays to Ne-20?
When Na-20 decays to Ne-20, it emits a beta-minus particle, which is essentially an electron. This is because in beta-minus decay, a neutron is converted into a proton, releasing an electron and an antineutrino.
What is the value of n for the level in which the electron originated is an electron in a hydrogen atom relaxes to the 4 level emitting a light of 114 tetra Hz?
The frequency of light emitted during a transition in a hydrogen atom can be calculated using the formula: ΔE = hf = E(final) - E(initial). Given that the frequency is 114 tetra Hz, we can calculate the energy difference and determine that the initial level (n) is 5.
Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
When an electron falls from n4 to n1, it releases more energy because it is transitioning between high energy states. This higher energy transition corresponds to a shorter wavelength of light being emitted, according to the energy of the photon being inversely proportional to its wavelength. In contrast, when an electron falls from n2 to n1, the energy released is less, resulting in a longer wavelength of light emitted.
When an electron drops from level 5 to level 1 a photon is emitted in what region?
When an electron drops from level 5 to level 1, a photon is emitted in the ultraviolet region of the electromagnetic spectrum. The energy released corresponds to the energy difference between the two electron levels, which is characteristic of ultraviolet light.

How is the change in electron energy related to the frequency of light emitted in electron transitions?
Its right in the book (in bold) and has a key next to it.
Why frequency of light never change when light changes medium?
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.
Does photoelectric effect take place below threshold frequency?
No, the photoelectric effect only occurs when the frequency of incident light is equal to or greater than the threshold frequency. Below the threshold frequency, photons do not possess enough energy to eject electrons from a material.
When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?
The energy of the electron decreased as it moved to a lower energy state, emitting a photon with a wavelength of 550 nm. This decrease in energy corresponds to the difference in energy levels between the initial and final states of the electron transition. The energy of the photon is inversely proportional to its wavelength, so a longer wavelength photon corresponds to lower energy.
A beta particle is a what created and emitted from an unstable nucleus?
NovaNet: A beta particle is simply a high speed electron.
Is it possible to create an EM wave with a frequency that changes e.g increases or decreases over time?
No. The frequency of an EM wave depends only on the source, and cannot be altered once it has been emitted.
When a neutron decays into a proton the electron is emitted from the nucleus what is this kind of radioactivity called?
If an electron is released from the nucleus (and not from an electron shell) then it would have been emitted by a neutron in beta decay. In beta-minus decay, a neutral neutron emits an electron and an anti-neutrino and becomes a proton; in beta-plus decay, a proton emits a positron and a neutrino and becomes a neutron.
Doppler effect with two people moving to each other?
In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.In this case, the frequency of a wave emitted by one person would increase (be perceived as having a higher frequency) by the other.
Is radioactive decay an electron?
No. An electron may be emitted in some cases, though.
What is emitted by an atom as a result of electron capture?
After electron capture a neutrino is released.
What particle is emitted when Na-20 decays to Ne-20?
When Na-20 decays to Ne-20, it emits a beta-minus particle, which is essentially an electron. This is because in beta-minus decay, a neutron is converted into a proton, releasing an electron and an antineutrino.
