What is the frequency and wavelength of a photon emitted during a transition from n 5 state to?
What are frequency and wavelength of a photon emitted during a transition from n=5 state to n = 2 state in hydrogen atom? As n1= 2 and n2 = 5, this transition gives rise to a spectral line in the Balmer series. A photon of wavelength 4 x 10-7 m strikes on metal surface, the work function of the metal being 2.13 eV.
What are the frequency and wavelength of a photon emitted during a transition from n 5?
λ=434 nm.
What are the frequency and wavelength of photon?
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.
What is the frequency of the emitted photon?
This equation is known as the Planck-Einstein relation. Substituting h with its value in J⋅s and f with its value in hertz gives the photon energy in joules. Therefore, the photon energy at 1 Hz frequency is 6.62606957 × 10−34 joules or 4.135667516 × 10−15 eV.
What are the frequency and wavelength?
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
What does the wavelength of light mean?
The wavelength of light is defined as “The distance between the two successive crests or troughs of the light wave”.
What is the wavelength of normal light?
Visible light is usually defined as having wavelengths in the range of 400–700 nm, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430–750 terahertz (THz).
What is the wavelength of light in vacuum?
five thousand angstroms
What electromagnetic radiation is harmful?
The electric and magnetic forces in EMFs are caused by electromagnetic radiation. There are two main categories of EMFs: Higher-frequency EMFs, which include x-rays and gamma rays. These EMFs are in the ionizing radiation part of the electromagnetic spectrum and can damage DNA or cells directly.
