A wave has a wavelength of 1.2 m and frequency of 3 Hz what is the wave speed

Speed of wave = 3.6 m/s

Explanation:

Given data:

Wavelength of wave = 1.2 m

Frequency = 3 Hz

Speed of wave = ?

Solution:

Formula:

Speed of wave = wavelength × frequency

by putting values,

Speed of wave = 1.2 m × 3s⁻¹ (Hz = s⁻¹)

Speed of wave = 3.6 m/s

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
