Question

Part C What will occur if light with a shorter wavelength than that in part b =( 91.1 nm) is used to excite the hydrogen atom? What will occur if light with a shorter wavelength than that in part (b) is used to excite the hydrogen atom?

A) If light with a wavelength shorter than 91.1 nm is used to excite the H atom, the excess energy will be devided to the kinetic and potential energy of the ejected electron.

B) If light with a wavelength shorter than 91.1 nm is used to excite the H atom, the excess energy will become the potential energy of the ejected electron.

C) If light with a wavelength shorter than 91.1 nm is used to excite the H atom, the excess energy will become the kinetic energy of the ejected electron.

D) If light with a wavelength shorter than 91.1 nm is used to excite the H atom, there will be not enough energy to eject an electron.

Answer 1

the correct anser is

answer )

If light with a wavelength shorter than 91.1 nm is used to excite the H atom, the excess energy will become the kinetic energy of the ejected electron.

because E =h or E= h C/​ ( C= or = C/)

from above we see that is inversely proportional to E

as decreases our energy increses and releses in form of kinetic energy and  of ejected electron .

correct option C)

If light with a wavelength shorter than 91.1 nm is used to excite the H atom, the excess energy will become the kinetic energy of the ejected electron.
