Due to the Doppler effect, waves from an approaching source (moving toward the observer) are observed as having a shorter wavelength than when they were emitted. Which of the following pairs could represent the kind of radiation emitted from a source rapidly approaching Earth and the kind of radiation it is detected as on Earth?
A
emitted as a gamma ray, observed as ultraviolet light
B
emitted as a microwave, observed as a radio wave
C
emitted as yellow light, observed as blue light
D
emitted as ultraviolet light, observed as infrared radiation

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
