discovery x-rays

They travel in straight lines. They remain undisturbed in an electric as well as magnetic field. They can pass through opaque objects such as black paper. They can affect a photographic plate. They are, in fact, electromagnetic waves of very short wavelengt..

Electron - Discharge Tube experiments - These experiments were conducted in detail by J.J. Thomson and he studied the passage of electricity through gases at extremely low pressure in a cylindrical glass tube. It was discovered that at extremely low pressure, gases become conductors of electricity ..

X-Ray Study of Crystals - In a crystalline solid, the constituent particles (atoms, ions or molecules) are arranged in a regular order. An interaction of a particular crystalline solid with X-rays helps in investigating its actual structure. Crystals are found to act as diffract..

Further experiments established the following properties of cathode rays. They travel in straight lines from the cathode to the anode. (When an object is placed in the path of a cathode ray in the discharge tube, the light gets blocked in the area of the object and fluorescen..

They are electromagnetic radiations like X-rays having very short wavelength, in the range of 10 -10 m to 10 -13 m. They affect photographic plate. They are unaffected by electric and magnetic fields. Their ionizing power is low, (about one hundredth of b - particles). T..

Which of the following describes the graph of the parametric equations x = 2 + t , y = 4 t + 3, t ≥ 0? => a line segment or a straight line or a circle or a ray..
