Problem #2: a) How many green photons
(wavelength = 500 nm) does it take to equal the energy of one gamma ray
photon (wavelength = 10-2 nm)?
b) How many of these gamma ray photons would it take to equal
the the energy required to light a 100-watt light bulb for one second (100
J)?
Problem #3: a)The public radio station
in Lewisburg broadcasts at a frequency of 100.1 MHz ("mega-hertz"). What
is the wavelength of these radio waves?
b)I'm driving in my car at 55 mph (24.6 m/s) directly toward
the radio station's broadcast tower. What is the frequency shift (due to
the Doppler Effect) in the signal my car radio receives? Is the received
frequency higher or lower than the broadcast frequency?
