X-ray-2

X-rays

What is the correct sequence of following electromagnetic radiation arranged in the increasing radiation in the increasing order of energy ? 1. X - rays 2. Visible light 3. gamma - rays Select the correct answer using the codes given below

Consider the following statements: 1. X-rays show transverse wave characteristics. 2. X-rays can eject electrons from certain metal surfaces 3. X-rays or 0.1 Å are harder than X-rays of 0.2Å. Which of the statements given above is/are, correct ?

Electrons are accelerated in television tubes through potential difference of about 10 KV. (1) The lowest wavelength of the emitted X-rays is 12.4 overset(@)A . (2) The lowest wavelength of the emitted X-rays is 1.24 overset(@)A (3) The highest frequency of the emitted X-rays is 2.4xx10^(8)Hz (4) The higher frequency of the emitted X-rays is 2.4xx10^(18)Hz

Statement-1: Gamma rays are more energetic than X-rays. Statement-2: Gamma rays are of nuclear origin but x-rays are produced due to sudden deceleration of high energy electrons while falling on metal of high atomic number.

If the minimum wavelength obtained in an X - ray tube is 2.5 xx 10^(-10) m , the operating potential of the tube will be
