UV radiations and X - rays are:
UV radiations are produced by the high energy transitions of the electrons in atoms. UV radiations have wavelengths ranging from 0.4 m m to 1nm. X - rays are produced in discrete wavelengths in individual transitions among the inner electrons of an atom.
When decelerated electrons are scattered to the target in coulidge tube equipment X - rays are produced.
X - rays are used in medical diagnosis called "Radiography". X - rays are used to cure the diseases the is called "Radiotherapy". X - rays are emitted in radio activity.

A ball of mass 0.7 kg is dropped vertically from a height of 10 m onto a concrete floor. The ball is observed to bounce a number of times before coming to rest. The coefficient of
Explain the working of a refrigerator A refrigerator is the reverse of a heat engine. Here the working substance extracts heat Q2 from the cold reservoir at temperature T2, som
Surface tension can be explained in given possible ways: (i) The property of a liquid on account of which it tends to keep minimum number of molecules in its free surface is d
If electrons are treated as classical particles,which statistics will they follow?
Michelson Morley Experiment The Michelson-Morley experiment was performed within the year of 1887 through Albert Michelson and Edward Morley at what is presently Case Western
torque
Depending upon the penetration power, there are two parts of X-rays Hard X-rays More penetration power More frequency of the order of ≈ 1019 Hz Lesser wavelength range
A trick with surface tension Get a used tin can and make five holes in it with a nail. The holes should be very close to the bottom of the can and about five millimetres apart.
WHY Surface tension increases when an highly soluble SUBSTANCE is dissolved in water WHILE IT DECREASES WHEN an weakly soluble substance is dissolved in water
