MCQ (Single Correct Answer)

-1

Energy levels A, B and C of a certain atom corresponding to increasing values of energy i.e. E_A < E_B < E_C. If $$\lambda $$₁, $$\lambda $$₂ and $$\lambda $$₃ are wavelengths of radioations corresponding to transitions C to B, B to A and C to A respectively, which of the following relations is correct?

$${\lambda _3} = {\lambda _1} + {\lambda _2}$$

$${\lambda _3} = {{{\lambda _1}{\lambda _2}} \over {{\lambda _1} + {\lambda _2}}}$$

$${\lambda _1} + {\lambda _2} + {\lambda _3} = 0$$

$${\lambda _3}^2 = {\lambda _1}^2 + {\lambda _2}^2$$

If M(A; Z), M_p and M_n denote the masses of the nucleus $${}_Z^AX,$$ proton and neutron respectively in units of u (1 u = 931.5 MeV/c²) and BE represents its bonding energy in MeV, then

M(A, Z) = ZM_p + (A $$-$$ Z)M_n $$-$$ BE

M(A, Z) = ZM_p + (A $$-$$ Z)M_n + BE/c²

M(A, Z) = ZM_p + (A $$-$$ Z)M_n $$-$$ BE/c²

M(A, Z) = ZM_p + (A $$-$$ Z)M_n + BE
