According to de-Brogile, matter should ...

According to de-Brogile, matter should exhibit dual behaviour, that is both particle and wave like properties. However, a cricket ball of mass 100 g does not move like a wave when it is thrown by a bowler at a speed of 100km/h. calculate the wavelength of the ball and explain why it does not show wave nature.

`lambda=(h)/(mv)`
`m=100 g=0.1kg." "v=100km//hr=(100xx1000m)/(60xx60s)=(1000)/(36)ms^(-1)`
`h=6.626xx10^(-23)Js" "lambda=(6.626xx10^(-34)Js)/(0.1kgxx(1000)/(36)ms^(-1))=6.626xx10^(-36)xx36m=238.5xx10^(-36)m`
Since the wavelength is very small, the wave nature cannot be detected.

When a particle is restricted to move along x-axis between x=0 and x=a , where alpha if of nenometer dimension, its energy can take only certain specific values. The allowed energies of the particle moving in such a restricted region, correspond to the formation of standing waves with nodes at its ends x=0 and x=a . The wavelength of this standing wave is related to the linear momentum p of the particle according to the de Broglie relation. The energy of the particle of mass m is related to its linear momentum as E=(p^2)/(2m) . Thus the energy of the particle can be denoted by a quantum number n taking values 1,2,3, ...( n=1 , called the ground state) corresponding to the number of loops in the standing wave.

de Broglie (1924) predicted that small particles such as electrons should show wave -like properties along with paticle character. The wave length (lamda) associated with particle of mass m and moving with velocity v is given as lamda=h/(mv) where 'h' is plank's constant. The wave nature was confirmed by Davisson and Germer's experiment and modified equation for calculation of lamda can be given as: lamda=-h/(sqrt(2Em)) where E= kinetic energy of particle. lamda=h/(sqrt(2dVm)) , where d= change of particle accelerated potnetial of V volt.

Estimation of frequency of a wave forming a standing wave represented by y = A sin kx cos t can be done if the speed and wavelength are known using speed = "Frequency" xx "wavelength" . Speed of motion depends on the medium properties namely tension in string and mass per unit length of string . A string may vibrate with different frequencies . The corresponding wavelength should be related to the length of the string by a whole number for a string fixed at both ends . Answer the following questions: Speed of a wave in a string forming a stationary wave does not depend on

Werner Heisenberg considered the limits of how precisely we can measure the properties of an electron or other microscopic particle. He determined that there is a fundamental limit to how closely we can measure both position and momentum. The more accurately we measure the momentum of a particle, the less accurately we can determine its position. The converse also true. This is summed up in what we now call the Heisenberg uncertainty principle. The equation si deltax.delta (mv)ge(h)/(4pi) The uncertainty in the position or in the momentum of a marcroscopic object like a baseball is too small to observe. However, the mass of microscopic object such as an electon is small enough for the uncertainty to be relatively large and significant. What would be the minimum uncetaintty in de-Broglie wavelength of a moving electron accelerated by potential difference of 6 volt and whose uncetainty in position is (7)/(22) nm?
