What is the frequency of 589 nm?
850 MHz
What is the frequency of this light? Since c is expressed in meters per second, we must also convert 589 nm to meters. One of the frequencies used to transmit and receive cellular telephone signals in the United States is 850 MHz.
What is the energy of ultraviolet radiation having a wavelength of 1.18 x 10 8 m?
1.68×10−17J.
What is the energy of a photon whose frequency is 2.22 x 10 14 Hz?
What is the energy of a photon whose frequency is 2.22 x 10^14 s^-1? where f is the frequency of the photon and h is Planck’s constant (6.626 x 10E-34 J s). Substituting f = 2.22 x 10E14 s-¹ gives E = 1.47 x10E-19 J (to 3 sf).
What is the wavelength in nm for a transition from N 6 to N 2 in the hydrogen atom?
| Electron Transition | Energy (J) | Wavelength (nm) |
|---|---|---|
| n=5 to n=2 | 4.58 x 10-19 | 434 |
| n=6 to n=2 | 4.84 x 10-19 | 411 |
| Lyman Series ( to n=1) | ||
| n=2 to n=1 | 1.632 x 10 -18 | 122 |

What is the energy of a 3.12 x 1018 Hz wave? 2.07 x 10-15 J 10.
What is the frequency of ultraviolet light with a 3.25×10 8m wavelength?
7. What is the wavelength of a 4.34 x 1015 /s wave? 10 = 5.36 x 103 goll RADIO Page 2 HW #2 – Light Problems Use the given equations to solve the following problems. nu (or new) is the frequency of a wave, and c is the speed of light (a constant equal to 3.0 x 10 m/s.)
What is the wavelength and energy of X ray photon whose frequency is?
X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 1016 to 1020 hertz (Hz).
What is the wavelength in nanometers of a photon emitted during a transition from Ni 6 to NF 2 state in the H atom?
A good starting point here will be to calculate the energy of the photon emitted when the electron falls from ni=6 to nf=2 by using the Rydberg equation. So, you know that when an electron falls from ni=6 to nf=2 , a photon of wavelength 410 nm is emitted.
Which is the unit of measurement for wavelength?
Wavelength (m) = Wave velocity (m/s) / Frequency (Hz) Wavelength represents the distance between two consecutive frequency wave peaks and is usually used to describe the electromagnetic spectrum. The measurement units for it available in the form are microns; mm; cm; m; km; inches and feet.
How is the velocity of a wave related to the wavelength?
Let’s take for instance the case of a wave with a frequency of 56 Hz going through a material at a speed of 168 m/s. The wavelength result is 3 m. Wave velocity (m/s) = Frequency (Hz) x Wavelength (m)
How does the frequency to wavelength calculator work?
This frequency to wavelength calculator helps you determine the wavelength of a waveform based on the frequency. It assumes that the wave is traveling at the speed of light which is the case for most wireless signals. The entry unit of frequency can be modified, the output wavelength is calculated in meters.
Which is the longest wavelength violet or red?
The spectrum of visible light has about numerous different colours having different wavelengths. The violet colour is said to have the shortest form of wavelength whereas red colour is said to have the longest wavelength. It can also be noticed in the below-given figure.
