When we study (4), or the study of matter and energy, we need to know two things to figure out how fast an object is going. First, we need to know how far the object traveled, or the (5). Second, we need to know how long it took the object to reach its destination, or the (6). By dividing the total distance by the total time, we can find the (7) of the object. This speed can be used to find the amount of (8) the ball has (the energy of motion).

The picture is not loading as it requires a sign in.
However, I can tell you how to solve this.

As the wavelength gets shorter (closer together), the frequency of the wave increases. 

Explanation:
The relation between frequency and wavelength can be described by the help of velocity as follows:
velocity = frequency * wavelength
This means that:
frequency = velocity / wavelength
Noting this equation, we will find that:
The frequency and the wavelength are inversely proportional to each other. This means that as the frequency increases, the wavelength decreases and vice versa.
Now, examining the choices given, we can find that the only statement showing the inverse relation between frequency and wavelength is:
As the wavelength gets shorter (closer together), the frequency of the wave increases. 

Hope this helps :)
