The `k_beta` X-rays from certain elements are given below. Draw a Moseley-type plot of `sqrt v` versus `Z` for `K_beta` radiation
Element Ne P Ca Mn Zn Br
Energy (keV) 0.858, 2.14, 4.02, 6.51, 9.57, 13.3.

Text Solution

Verified by Experts

K_b radiation is when the e jumps from
` n=3 to n=1 `
(Here n is Principal quantum number)
` DeltaE=hf `
` =Rhe(Z-h)^2(1//2^2-1//3^2) `
` rArr sqrtf=(9Re)/8(Z-h) `
` :.(sqrt(f))alphaZ `
Second method
We can directly get value of f by
` hf=Energy `
` rArr f=(Energy (in keV)/h) `
thus we have to find out sqrtf and draw the same graph as above.

In the photoelectric effect the electrons are emiited instantaneously from a given metal plate when it is irradiated with radiation of frequency equal to or greater than some minimum ferquency, is called the threshold frequency.According to Planck's idea, light may be considered to be made up discrete particles called photons.Each photon carries energy equal to hv.When this photon collides with the electron of the metal, the electron acquires energy of the emitted electron is given by : hv=K.E_("maximum")+PE=(1)/(2)m u^(2)+PE If the incident rediation is of threshold frequency the electron will be emitted without any kinetic energy i.e hv_(0) :.(1)/(2)m u^(2)=hv-hv_(0) A plot of kinetic energy of the emitted electron versus frequency of the incident radiation yields a straight line given as : A laser producting monochromatic lights of different wavelenght is uesd to eject electrons from the sheet of gold having threshold frequency 6.15xx10^(14)s^(-1) Which of the following incident rediation will be suitable for the ejecting of electrons ?

For his 18th birthday in February Peter plants to turn a hut in the garden of his parents into a swimming pool with an artifical beach. In order to estimate the consts for heating the water and the house , peter obtains the data for the natural gas combustion and its price. What is the total energy (in MJ) needed for Peter's "winter swimming pool" calculated in 1.3 and 1.4? How much natural gas will he need, if the gas heater has an efficiency of 90.0% ?

When the voltage applied to an X-ray tube increased from V_(1)=15.5kV to V_(2)=31kV the wavelength interval between the K_(alpha) line and the cut-off wavelength of te continuous X-ray spectrum increases by a factor of 1.3 . If te atomic number of the element of the target is z. Then the value of (z)/(13) will be: (take hc=1240eVnm and R=1xx(10^(7))/(m))
