Calculate the wavelength of emr that has a frequency of 9.50 x 10^8 hz

0.316 m

Explanation:

The wavelength of an electromagnetic radiation is given by the formula :

Speed of the electromagnetic radiation/ frequency of the electromagnetic radiation

Speed of electromagnetic radiation is given by 3*10^8 m/s

Frequency of the electromagnetic radiation is 9.50*10^8 Hz

Substituting the relevant values in the above formula:

3*10^8/9.50*10^8 = 3/9.5=0.316 m

So the required wavelength is 0.316 m

3.helium

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
