Please help me

Sally sits and observes an ocean wave
A. She times waves and finds that it takes 32.8 s for 6.00 waves to pass by. What is the period of
the wave?

B. What is the frequency of the wave?

C. She also notices that there is a distance of 1.82 m between crests. What is the wavelength of
the wave?

D. Finally, she records that from the highest point on a wave to the lowest point is a distance of
0.742 m. What is the amplitude of the wave?

E. Calculate the velocity of the wave.

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.
