A wave with a period of 1⁄3 second has a frequency of D. 3 Hz. To
calculate this we will use the formula that represents the correlation
between a frequency (f) and a time period (T): T = 1/f. Or: f = 1/T. The
unit for the time period is second "s" while the unit for frequency is
Hertz "Hz" (=1/s). We know that T = 1/3 s. That means that f = 1/(1/3s) =
3 1/s = 3 Hz.
Explanation:
According to the general theory of relativity, spacetime curves due to the energy it contains. Since mass is a form of energy, "create" gravity. That is, gravity is the effect observed as a consequence of the curvature of spacetime. Therefore, gravity curves the path of light because it curves the space through which light passes.
The answer is going to be B
