Question

1. Why alpha, beta and gamma rays are not considered in ER spectrum?
2. How can we notice that electron(s) are lost during photoelectric effect?
3. We know that energy of striking Photons = binding energy+kinetic energy of ejected electron. Suppose the energy of striking Photon is greater than the binding energy but less than the kinetic energy to agent the electron, then where will the electron reside in the atom?
4. What is diffraction and interference?
5. Atomic spectra we use either hydrogen or hydrogen like ions, does the spectra depends upon the number of electron if so why?
6. How many photons of light having a wavelength 400 nm are necessary to provide 1 J of energy?
7. A 100 watt bulb emits electro-magnetic light of wavelength 400 nm. Calculate the number of photons emitted per second by the bulb.

Answer 1

Answer:

binding energy+kinetic energy of ejected electron. Suppose the energy of striking Photon is greater than the binding energy but less than the kinetic energy to agent the electron, then where will the electron reside in the atom

Explanation:

ejected electron. Suppose the energy of striking Photon is greater than the binding energy but less than the kinetic energy to agent the electron, then where will the electron reside in the atom?
