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)
Using principles of special theory of relativity derive mass energy relation, illustrate it with an example. A beam of particle of half life 2.0 x 10-8 sec. travels in a laborat
Ionisation: If the amount of external energy is large enough the valence electron can gain sufficient kinetic energy (energy of movement) to be removed completely from its atom
What is the maximum wavelength of the visible spectrum so that 3 rd order spectrum can be obtained by a plane diffraction grating having 5654 lines/cm?
A ball with an initial momentum of 6.00 kg.m/s bounces off a wall and travels in the opposite direction with a momentum of 4.00 kg.m/s. What is the magnitude of the impulse ac

Describe how the law of conservation of energy holds good in light interference pattern
Rydberg constant (Rydberg): A constant that governs the relationship of the spectral line features of an atom by the Rydberg formula. For hydrogen, it is about 1.097 x 10 7 m
Explain about the Homojunction Laser in brief. Homojunction Laser: Assume that GaAs be doped with T providing n-type material and with Ge providing p-type material. In forwa
Reverse Bias: When P-types material of a semi conductor diode is linked a negative potential and the n-type material is linked at positive potential of a voltage source, the di
Contact forces: types of forces that result when the two interacting objects are apparent to be physically linking each other. Ex: frictional forces, tensional forces, normal f
