What is the longest wavelength radiation capable of ionizing?

1 Answer
Hence, the energy of the incident photon =hv = hc/λ = 13.6eV.λ = (6.6 x 10-34 x 3 x 108/13.6 x 1.6 x 10-19)= 0.910 x 10-10 m.This radiation is in ultraviolet region.

What is the longest wavelength of light that can be emitted by a hydrogen atom?

According to the calculations, the longest wavelength of the electromagnetic radiation emitted by the hydrogen atom is 656 nm which is produced by the transition from n=3 to n=2.

What wavelength of light is required to ionize a hydrogen atom?

Truong-Son N. 91.2 nm .

What is the longest wavelength photon?

The red light has the longest wavelength, lowest energy, and lowest frequency. The shorter the drop from one energy level to another, the less energy, in the form of light/photons is emitted.

How much energy in joules does it take to ionize a hydrogen atom what wavelength of light would be required to ionize a hydrogen atom?

This transition is part of the Lyman series and takes place in the ultraviolet part of the electromagnetic spectrum. This means that in order to remove the electron from the ground state of a hydrogen atom in the gaseous state and create a hydrogen ion, you need to supply 2.181⋅10−18 J of energy.

How do you find the longest wavelength?

The longest wavelength, as everyone mentioned, comes from the work function. Using the value of energy from the work function, solve for wavelength using E = h(c)/(wavelength).

What is the maximum wavelength?

The maximum wavelength of light for photoelectric effect from a metal is 200 nm. The maximum kinetic energy of electron which is emitted by the radiation of wave length 100 nm will be: (1) 12.

What is the longest wavelength of light that would cause electrons to be emitted from the cathode?

The longest wavelength of light that will cause an electron to be emitted from a metal is 520 nm.

What is the maximum wavelength of light capable of removing an electron?

The maximum wavelength of light that can remove an electron from a lithium atom is equal to 4.279⋅10−7m . So, you know that the work function of lithium, which is the energy needed to remove an electron from an atom located at the surface of the metal, is equal to 279.7 kJ/mol.

How do you determine the longest and shortest wavelength?

For Lyman series, n1=1.For shortest wavelength in Lyman series (i.e., series limit), the energy difference in two states showing transition should be maximum, i.e., n2=∞.For longest wavelength in Lyman series (i.e., first line), the energy difference in two states showing transition should be minimum, i.e., n2=2.

How do you find the ionization energy of hydrogen?

Explanation: For the Hydrogen Atom, ionization from the ground state where ni=1 => ΔEizn=2.18×10−18J(1(∞)2−1(1)2) = −2.18×10−18Joules to remove the electron from n = 1 energy level to n=∞ .

What is the longest to shortest wavelength?

Order is as follows (shortest to longest wavelength): Gamma, X-Rays, UV, Visible, Infrared, Microwaves, Radio Waves.

Which of the following transitions in a hydrogen atom represents emission of the longest wavelength photon?

Based on the obtained values, the transition that represents the emission of the longest wavelength photon is n = 5 to n = 4 (i.e., 4050 nm).

Which transition in the hydrogen atom results in the absorption of a photon with the longest wavelength?

The absorption with longest wavelength is n=7→n=8 .

What is the longest wavelength of light the atom will absorb?

The longest wavelength of light absorbed by a hydrogen-like atom is 2.48 nm.

What is the longest wavelength of photon?

That means a wavelength of 6200 to 62000 miles. There is no lower limit, but 3 to 30Hz is a practical limit as photon energies are gettting really small, close to the noise level.
