What is the wavelength of electromagnetic radiation


Discuss the below:

1. a. What is the wavelength (in meters) of electromagnetic radiation broadcast by an FM radio station with a frequency of 106.1 MHz?

b. What is the frequency (in Hertz) of electromagnetic radiation with a wavelength of 532.6 nm?

2. (Quantum Effects and Photons)

a. A laser emits light with a frequency of 1.17 x 1012 s-1. What is the energy of one photon of the radiation from this laser?

b. If the laser emits a pulse of energy containing 10.5 x 1015 photons, what is the total energy of that pulse?

c. If the laser emits 1.7 x 10-3 J of energy during a pulse, how many photons are emitted during the pulse?

3. (Quantum Effects and Photons)

a. Calculate the smallest increment of energy (a quantum) that can be emitted or absorbed at a wavelength of 756 nm.

b. What wavelength of radiation has photons equal to 1.25 x 10-18J?

c. In what region of the electromagnetic spectrum would you find the radiation in part b?

4. (The Bohr Theory/ Hydrogen Atom)

a. What is the wavelength of light emitted from a hydrogen atom when the electron moves from the n = 4 level to the n = 1 level? Which region of the electromagnetic spectrum does this light correspond to?

b. What is the wavelength of light emitted from a hydrogen atom when the electron moves from the n = 7 level to the n = 6 level? Which region of the electromagnetic spectrum does this light correspond to?

5. (Quantum Numbers) Briefly explain why each of the following is not a possible set of quantum numbers for an electron in an atom.

a. n = 2, l = 2, ml = 0, ms = +1/2

b. n = 0, l = 0, ml = 0, ms = -1/2

c. n = 1, l = 0, ml = 1, ms = +1/2

d. n = 3, l = 1, ml = -1, ms = 0

e. n = 2, l = -1, ml = 0, ms = -1/2
