MCQ
Which is the correct expression for half-life
  • A
    ${(t)_{1/2}} = \log \,2$
  • B
    ${(t)_{1/2}} = \frac{\lambda }{{\log \,2}}$
  • C
    ${(t)_{1/2}} = \frac{\lambda }{{\log \,{\rm{2}}}}(\,2.303)$
  • ${(t)_{1/2}} = \frac{{2.303\,{\rm{ log\,2}}}}{\lambda }$

Answer

Correct option: D.
${(t)_{1/2}} = \frac{{2.303\,{\rm{ log\,2}}}}{\lambda }$
d
(d)${T_{1/2}} = \frac{{{{\log }_e}\,2}}{\lambda } = \frac{{2.303\,{{\log }_{10}}\,2\,}}{\lambda }$

Given below are two statements : one is labelled as Assertion $A$ and the other is labelled as Reason $R$.

Assertion $A :$ For a simple microscope, the angular size of the object equals the angular size of the image.

Reason $R$ : Magnification is achieved as the small object can be kept much closer to the eye than $25\, cm$ and hence it subtends a large angle.

In the light of the above statements, choose the most appropriate answer from the options given below:
