A 1.1-kg uniform bar of metal is 0.40 m long and has a diameter of 2.0 cm. When someone bangs one end of this bar, a 1.5 MHz shock wave is travels along the length of the bar and reaches the other end in 0.12 ms.
 
  What is the wavelength of the shock wave in the metal? A) 2.2 mm
  B) 2.6 mm
  C) 3.0 mm
  D) 3.4 mm
  E) 3.8 mm

Question 2

Two sources emit beams of light of wavelength 550 nm. The light from source A has an intensity of 10 W/m2,
 
  and the light from source B has an intensity of 20 W/m2. This is all we know about the two beams. Which of the following statements about these beams are correct? (There could be more than one correct choice.)
  A) Beam B carries twice as many photons per second as beam A.
  B) A photon in beam B has twice the energy of a photon in beam A.
  C) The frequency of the light in beam B is twice as great as the frequency of the light in beam A.
  D) A photon in beam B has the same energy as a photon in beam A.
  E) None of the above statements are true.
