I assume that you want to find out what's the frequency is.

Number of oscillation = 6  which being done in 30 second.

which means the time period for 1 oscillation is 30 second/6 = 5 second


Frequency = 1/time period
                 = 1/5 Hertz

Hope this help

Calculate the minimum wavelength (λ0) for the continuous spectrum of X-rays emitted when.. a) 30-kV electrons strike a cobalt (C
Sholpan [36]

Explanation:

The relationship between the wavelength and the potential difference V is given by :

\lambda=\dfrac{h}{\sqrt{2me}}\times \dfrac{1}{\sqrt{V}}

Putting the values of known parameters,

\lambda=\dfrac{12.28}{\sqrt{V} }\times 10^{-10}\ m

(a) V=30\ kV=30000\ V

\lambda=\dfrac{12.28}{\sqrt{30000} }\times 10^{-10}\ m

\lambda=7.08\times 10^{-12}\ m

(b) V=60\ kV=60000\ V

\lambda=\dfrac{12.28}{\sqrt{60000} }\times 10^{-10}\ m

\lambda=5.01\times 10^{-12}\ m

Hence, this is the required solution.
