Question

Penetrating power of X-rays can be increased by : 

(a) increasing the potential difference between anode and cathode 

(b) decreasing the potential difference between anode and cathode 

(c) decreasing the current of cathode filament 

(d) increasing the current of cathode filament

Answer 1

Correct option (a) increasing the potential difference between anode and cathode

Explanation:

We know that by increasing the potential difference between anode and cathode, X-rays having short wavelength will be produced which have more penetrating power.
