Answer:
It becomes shorter
Explanation:
A wave, such as a Soundwave, controls volume based on it's Wavelength. A Louder sound has a shorter wavelength, a softer sound has it's waves spread out more. Amplitude is simply a fancy name for Volume in Amps. When amplitude increases, the volume increases. Thus, waves become shorter.
Answer: The molecular formula will be 
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= 13.65 g
Mass of F = 86.35 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of F=
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C = 
For F = 
The ratio of C : F= 1: 4
Hence the empirical formula is 
The empirical weight of
= 1(12)+4(19)= 88g.
The molecular weight = 88.01 g/mole
Now we have to calculate the molecular formula.

The molecular formula will be=
