Suppose a single photon strikes an electron in some material, knocking it out of its atom. Which of the following statements are true concerning the scattered photon? a. The scattered photon has greater energy than the incident photon.
b. The scattered photon has a shorter wavelength than the incident photon.
c. The scattered photon has a longer wavelength than the incident photon.
d. The scattered photon has less energy than the incident photon.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Smallest intensity of a stimulus that you can detect 50 percent of the time is

Which property is expressed in distance units? o a. period o b. wavelength o c. speed o d. frequency
