3. a) Find the de Broglie wavelength of a 1.00 keV proton. Is a relativistic calculation needed? B) Find the de Broglie wavelength of a 1.00 GeV proton. Is a relativistic calculation needed? 4. (book #
Chapter 3 Homework Solutions
1. (book #3)
2. (book #4)
3. a) 1 keV is small compared to proton rest energy of ~1 GeV so nonrelativistic is fine.

Chapter 2 Homework Solutions
1. Planck's constant gives a measure of the energy at which quantum effects are observed. If Planck's constant had a larger value, while all other physical quantities such as, speed of light, remained the same; quantum effects
Chapter 2 Homework Problems
1. If Planck's constant were larger than it is, would quantum phenomena be more or less conspicuous than they are now? 2. (a)A typical AM radio frequency is 1000kHz. What is the energy in eV of photons of this frequency? (b) Wh
Chapter 1 Homework Solutions
1. All else being equal, relativistic phenomena would be less conspicuous if the speed of light were larger. We would have to obtain an even larger speed than we do now for relativistic effects to manifest themselves.
