The energy that should be added to an electron,to reduce its de-Broglie wavelengths from 10^(-10)m to "=0.5times10^(-10)m ,will

Electronicmagnetic wave have wide range of wavelengths starting from 10^-14m to 10^3m . The em wave of different wavelength are used for different purpose. The gamma -rays which have lowest wavelength are least energetic. Read the above the passage and answer the following questions: (i) What are more energetic waves, x-rays or ultra violet rays? (ii) Why are teh radio waves not used to detect fracture in the bones of a human body when they can deliver a message at large distances? (iii) What are the basic values displayed by the above study?
