Question

Can we say that speed = frequency( that is v = nu)
Give reason

Answer 1

speed of sound = V

wavelength = λ

frequency = v

the time period of a wave is represented by = T = 1/v

In time T, a distance of wave length v is covered

so the speed of sound = V = λ/T

or V = λv

Answer 2

Explanation:

Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. In the later case calcium carbonate is derived from the mixture, forming a grade of product called "precipitated calcium carbonate,” or PCC.
