Kinetic energy of electron =30 eV
Acccording to the question , 10% of this energy is converted to photon which is given by
`(10)/(100)xx30=3 kV`
`:. " " lambda_("min")("in"Å)=(12375)/(V("in volt"))=(12375)/(3xx10^3)=4.12Å`
Also, `" " V("max")=(c)/(lambda_("min"))=(3xx10^(8))/((4.12xx10^(-10)))=7.2xx10^(17)Hz`

An electron with speed v and a photon with speed c have the same de-Broglic wavelength. If the kinetic energy and momentum of electron is `E_(e)` and

Correct Answer - B `(E_(e))/(E_(p))=((1)/(2)mv^(2))/(hupsilon)=(1)/(2)vxx(mv)/(h).(h)/(hupsilon)` But `(h)/(mv)=(h)/(hupsilon)` `:.(E_(e))/(E_(ph))=(1)/(2)v[(mv)/(h).(h)/(hupsilon).(c)/(c)]=(v)/(2c)`

The energy of gamma `(gamma)` ray photon is `E_(gamma)` and that of an X-rays photon is `E_(X)`. If the visible light photon has an energy of `E_(v)`,

Correct Answer - C `E_(gamma) ge 100 keV, E_(X) = 100 eV` to `100 keV`. So, we can say that `E_(y) gt E_(x) gt E_(v)`,

An electron collides with a fixed hydrogen atom in its ground state. Hydrogen atom gets excited and the colliding electron loses all its kinetic energ

Correct Answer - C Excitation upto `n=3` is required so that visible length is emitted upon de-excitation. So required energy `=13.6 (1-1/9)=12.1 eV`
