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 (0.1Å - 4Å)
Soft X-rays
Less penetration power
Less frequency of the order of ≈1016 Hz
More wavelength range (4Å - 100Å)
friction is a necessary evil?
how does a magnifying glass work to produce a large or smaller image?
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
Describe specific charge? Desfine Thomson's experiment to calculate e/m of an electron with relevant theory.

1. How fast must an object travel for its total energy to be (a) 1% more than its rest energy and (b) 99% more than its rest energy. 2. A proton is moving with a constant speed
(i) These are positive ions having similar mass if the experimental gas does not have isotopes. However if the gas has substances then positive pulses are group of positive ions ha
Coulomb's law (C. de Coulomb) The primary law for electrostatics is analogues to Newton's law of universal gravitation. This states that the force among two point charges is p
