Frequency of the wave is 2 per second
Explanation:
- Frequency is the number of times waves pass at a particular point of time. Here, given time period = 3 s and number of waves that pass in 3 seconds = 6. Find the frequency of the wave per second.
- Frequency is given by the formula
f = 1/T, where f is the frequency and T is the time period
- For 3 seconds, frequency is 6
3 seconds ⇒ 6 waves
⇒ 1 second = 6/3 = 2 waves per second
Answer:
valence shell electron pair conversion theory (VSEPR)
Explanation:
The theory of the repulsion of the electronic pairs of the valence layer (VSEPR) Unlike the ionic bond, the covalent bond is directional. The shape of a molecule explains an essential part of its properties. The theory of the repulsion of the electronic pairs of the valence layer (VSEPR) makes a simple addition to Lewis's ideas that allows us to foresee the shape of a given molecule: “The electronic pairs repel each other, so that they place as far as possible from each other. ”
