What effect would lower wavelength have on the emitted photoelectrons?
Lowering the wavelength of incident light increases its energy, which in turn can increase the kinetic energy of the emitted photoelectrons. This is in line with the photon energy equation E=hf, where E is energy, h is Planck's constant, and f is frequency (which is inversely proportional to wavelength).
What is the wavelength of the photon emitted when a hydrogen atom goes from the second energy level to the first energy level?
The wavelength of the photon emitted can be calculated using the Rydberg formula: 1/wavelength = R(1/n1^2 - 1/n2^2), where R is the Rydberg constant, n1 is the initial energy level (2 in this case), and n2 is the final energy level (1 in this case). Plugging in the values gives the wavelength of the photon emitted.
How do you calculate wavelength using the Bohr model for Hydrogen Atom?
You can calculate the wavelength of light emitted from a hydrogen atom using the Rydberg formula: 1/λ = R(1/n₁² - 1/n₂²), where λ is the wavelength, R is the Rydberg constant, and n₁ and n₂ are the initial and final energy levels of the electron.
In visible light color is an indication of?
In visible light, color is an indication of the wavelength of light that is being reflected or emitted by an object. Different colors correspond to different wavelengths of light, with red having the longest wavelength and violet having the shortest.
A blackbody curve relates the wavelength of emitted light to?
the intensity of radiation emitted at that wavelength, giving a characteristic spectral distribution that depends only on the temperature of the object emitting the light.
What is the emission wavelength equation used to calculate the specific wavelength of light emitted by a substance?
The emission wavelength equation used to calculate the specific wavelength of light emitted by a substance is c / , where represents the wavelength, c is the speed of light in a vacuum, and is the frequency of the light emitted.
Which transition occurs when light wavelength of 486 nm is emitted by a hydrogen atom?
The transition from energy level 4 to energy level 2 occurs when a hydrogen atom emits light of 486 nm wavelength. This transition represents the movement of an electron from a higher energy level (n=4) to a lower energy level (n=2), releasing energy in the form of light.
What is hydrogen shine?
The hydrogen line or "shine" is the frequency (1420.40575177 MHz) or wavelength (21.10611405413 cm) of electromagnetic energy emitted by an excited hydrogen atom. This is not a "shine" in the sense of visible - it is in the microwave frequency range. It is useful in radio astronomy because it passes through dust clouds that block visible light.
A light is emitted from a laser.its frequency is 630THz.what is the wavelength and color?
You can get the wavelength by dividing the speed of light by the frequency. Don't forget that THz means 10 to the power 12 Hz.
How can you calculate the frequency of a photon emitted by hydrogen atom given the energy level transition that happens?
To calculate the frequency of the light emitted when an electron in a hydrogen atom makes a transition, simply use change in E = (-2.18*10^-18 J)[1/(nf)^2 - 1/(ni)^2]. Then convert the energy E to frequency using f = E/h where h is Planck's constant 6.626*10^-34 J*s.
What is the frequency of light emitted by a laser pointer whose wave is 670 nm?
The frequency of light emitted by a laser pointer with a wavelength of 670 nm can be calculated using the formula: frequency = speed of light / wavelength. Plugging in the values, we get frequency = 3x10^8 m/s / (670x10^-9 m) = 4.48x10^14 Hz.
What wavelength should the astrophysicist look for to detect a transition?
The astrophysicist should look for the specific wavelength of light that corresponds to the energy difference between the initial and final states of the transition they are trying to detect. This is typically achieved through spectroscopy, which allows them to identify the exact wavelength of light emitted or absorbed during the transition.
A sample of zirconium emitted x-rays of wavelength 0.786 Å Calculate the frequency of this radiation?
1,2722.1010 Hz
What is the energy in cm-1 of the photon emitted during the transition of an electron in a hydrogen atom from the n3 to n2 energy level?
The energy of the photon emitted during the transition of an electron in a hydrogen atom from the n3 to n2 energy level is approximately 364.5 cm-1.
How can we calculate the wavelength of the photon emitted in a given scenario?
To calculate the wavelength of a photon emitted in a given scenario, you can use the formula: wavelength speed of light / frequency of the photon. The speed of light is approximately 3.00 x 108 meters per second. The frequency of the photon can be determined from the energy of the photon using the equation E hf, where E is the energy of the photon, h is Planck's constant (6.63 x 10-34 joule seconds), and f is the frequency of the photon. Once you have the frequency, you can plug it into the formula to find the wavelength.
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 wave with the longest wavelength and the lowest frequency are?
Radio waves have the longest wavelength and the lowest frequency among all types of electromagnetic waves. They are used in communication and are emitted by sources like radio stations and cell phones.
