<h2>Frequency</h2>
Explanation:
Wave frequency is the number of waves that pass a fixed point in a given amount of time.
Wave speed is the speed at which a wave travels.
Let the wave speed be ![v](https://tex.z-dn.net/?f=v)
Let the wave frequency be ![f](https://tex.z-dn.net/?f=f)
Let the wave length be ![l](https://tex.z-dn.net/?f=l)
The wave speed,frequency and wave length are related by the equation
.
When
increases,
increases on the other side to maintain equality when no other property is changing.
Answer:
No. Of Moles of zinc = m/Ar
= 13/ 65.38 = 0.198 moles
From balanced equation, Mole ration between CuSO4 and Zn is 1 : 1
So only 0.198 moles of CuSO4 reacts, it is in excess
Mass = no of Moles X Mr
Mass = 0.198 X 159.5 = 31.59 grams
Volume = mass m denisty
Volume j 31.59 / 3.6 = 8.78 ml
