1/t=2.18-10^-18^J
____________ (1/n_f_^2^ -1/n_f_^2^)=
hc
2.18*10^-18^J/(6.63*10^-34^Js)(3.00*1//0^8^m/s)(1/1^2^-1/1^2^)
=1.10*10^7^/m (1-1/9)=1.10*10^-7^/m(8/9)
=9.74*10^6^/m
t=(9.74*10^6^/m)^-1^=1.03*10^-7^m=103nm

Why is a shorter wavelength of light emitted when an electron falls from n equals 4 to n equals 1 than when an electron falls from n equals 2 to n equals 1?
Shorter wavelength = more energy. The farther the electron falls, the more energy that will be emitted.
What wavelength lambda should the astrophysicist look for to detect a transition of an electron from the n equals 7 to the n equals 3 level?
1005 m
How To find wavelength?
Wavelength times frequency equals 'the speed of light'. so wl = c/f
Frequency multipled by hertz equals speed?
No; hertz is frequency.Frequency times wavelength equals speed of travel.
Frequency equals speed divided by what?
Frequency = speed divided by wavelength

Shorter wavelength = more energy. The farther the electron falls, the more energy that will be emitted.
What is the wavelength and frequency of a photon emitted during a transition from n equals 5 to n equals 2 in hydrogen atom?
Drops to the ground state. Use this formula. Hydrogen has a 1 Z number. Frequency = (3.29 X 1015 Hertz) * Z2 * (1/Nf2 - 1/Ni2) To keep it positive, Frequency = (3.29 X 1015 Hertz) * 12 * (1/22 - 1/02) = 8.23 X 1014 Hertz emitted -------------------------------------

1005 m
What is the wavelength of a photon that will induce a transition from the ground state to the n equals 4 state in hydrogen?
That is the "gamma" line of the Lyman series: 94.97 nanometers.
Frequency divided by the speed of light equals?
That would be the reciprocal of wavelength.( 1 ) divided by (wavelength) .
Determine the end value of n in a hydrogen atom transition if the electron starts in n equals 4 and the atom emits a photon of light with a wavelength of 486nm?
The end value of "n" is 2.
How do you calculate red shift?
The spectrum of light emitted from heated hydrogen has dark lines, caused by the absorption of a very narrow wavelength band of light. These dark lines always take the same location relative to each other. If all the lines in an object's spectrum are shifted by the same amount, towards the red end of the visible spectrum, then the light is "red shifted." The amount of the shift is often described with a number 'z', where z equals the shift in wavelength divided by the wavelength as originally emitted by the object.
Does longer wavelength mean higher frequency?
No. Longer wavelength means lower frequency.When you multiply wavelength by frequency, the product is always the same.
Are frequency and wavelength related?
Yes, velocity equals the product of frequency times wavelength, v=fw.
What is the formula relating speed of light frequency and wavelength?
the speed of light equals the frequency multiplied by the wavelength.
How To find wavelength?
Wavelength times frequency equals 'the speed of light'. so wl = c/f
What is the relationship between the frequency and the wavelength and angular velocity of electromagnetic wave?
Velocity equals frequency times wavelength
