## Constants of Quantum Physics

**Instructions:**
Read each question carefully. Choose the answer that best fits the question. Short answer response questions must be responded to in complete sentences. If the question involves calculations, you must show all your math work.

1.

In quantum mechanics, the energy E of a charged atomic oscillator in the wall of a black body, is proportional to the frequency, ν, of its associated electromagnetic wave. What is the constant of proportionality?

- Boltzmann constant
- Planck’s constant
- Avogadro constant
- Quantum Gas constant

2.

The value of the Stefan–Boltzmann constant is given in SI units by .

- [math]5.670373(21)xx10^-8Wm^-2K^-4[/math]
- [math]1.054xx10^-34Js[/math]
- [math]6.626xx10^-34Js[/math]
- [math]7.5657xx10^-16Jm^-3K^-4[/math]

3.

Rydberg’s constant is expressed in the formula:

- [math] (h^2)/((m_e)(e^2)(k_e))[/math]
- [math]((2pi^5)(k_B^4))/((15h^3)(c^2))[/math]
- [math]((e^2)(k_e))/(2alpha_0)[/math]
- [math]((m_e)(e^4))/((8)(epsilon_0)^2(h^3)(c))[/math]

4.

The Stefan–Boltzmann constant allows for temperature (K) to be converted to units for , ([math]W/(m^2)[/math]), which is power per unit area.

- work
- intensity
- frequency
- proportionality

5.

Which of the following represents Planck's constant, h?

- [math]6.626 xx 10^-34 J•s[/math]
- [math]6.626 xx 10^-32 J•s[/math]
- [math]6.626 xx 10^-31 J•s[/math]
- [math]6.626 xx 10^-30 J•s[/math]

6.

The value of Rydberg's constant expressed in SI units is: .

7.

constant can be used to measure the amount of heat that is emitted by a blackbody, which absorbs all of the radiant energy that hits it, and will emit all the radiant energy.

- Planck's
- Stefan-Boltzmann's
- Boltzmann's
- Rydberg's

8.

constant represents the limiting value of the highest wave number of any photon that can be emitted from the hydrogen atom.

9.

What is the Planck relation for a photon?

- [math] E = (hc)/lambda [/math]
- [math]E = hclambda[/math]
- [math] E = h c^2 [/math]
- [math] E = c/h [/math]

10.

The Rydberg constant represents the wave number of the capable of ionizing the hydrogen atom from its ground state.
