No. That's the description of the wave's 'frequency'.
Refraction of a wave is its behavior when it crosses
the boundary between two different media.

Explanation:
kinetic energy is energy an object has due to its movement. for instance, if someone was riding down a hill, when the motion of the bike begins to decrease so does the kinetic energy

<u>Answer:</u>
Mass of combined products = 20.4 grams
Mass of combined product and Erlenmeyer flask = 136 grams
<u>Explanation:</u>
By law of mass conservation, mass cannot be destroyed or created. So mass before reaction is mass after reaction.
Mass of lead(II) nitrate = 15.6 grams
Mass of potassium iodide = 4.8 grams
Mass of the Erlenmeyer flask = 115.6 grams
Mass of reactants = 15.6 + 4.8 = 20.4 grams
So mass of products = 20.4 grams
Mass of combined product and Erlenmeyer flask = 115.6 + 20.4 = 136 grams
