Question

Prompt

The function

f (x) = 600 (0.5)^{\frac{x}{11}}

gives the predicted intensity of a beam

f (x)

in number of photons in the beam,

x

millimeters below the surface of a certain material. What is the best interpretation of

f (11) = 300

A beam at the surface of the material has a predicted intensity of 11 photons in the beam.

A beam at the surface of the material has a predicted intensity of 300 photons in the beam.

A beam 11 millimeters below the surface of the material has a predicted intensity of 300 photons in the beam.

A beam 300 millimeters below the surface of the material has a predicted intensity of 600 photons in the beam.
