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)
the centre of oscillation of a meter stick suspended about a transverse axis is located at the 10cm mark.Determine at what other positions could the meter stick be suspended and ha
Q. Why X-rays are not used in microscopes? 1) The wavelength of X-rays is slighter than that of the visible light. 2) X-rays can't be focussed as visible radiations are foc
a) A uniform mild steel ring has a diameter of 50mm and a cross-sectional area of 1cm 2 . Determine the mmf essential to produce a flux of 50µWb in the ring. (b) I
Write the symbol sad truth table of an AND gate define how this gate is realised in practice by using two diodes.
Q. Give the differences between hard X-rays and soft X-rays.
Ultraviolet catastrophe: A shortcoming of the Rayleigh-Jeans formula, that tries to explain the radiancy of a blackbody at several frequencies of the electromagnetic spectrum.
Corkscrew Rule: Knowing the direction of the current, it is possible to determine the direction of the magnetic field using Maxwell's Corkscrew rule, usually abbreviated to the
What is Rdiography.
how semiconductor diode act as rectifier?
Assumptions: Kinetic Energy=KE, Potential Energy=PE m=mass of the skateboarder=55 kg, Velocity v=1.80m/s So ,Initial Energy(KE) of the skateboarder=mv 2 /2 = 0.5* 55 * (1.8)^
