MCQ
Ratio of energy of photon of wavelength $3000\,\mathop A\limits^o $ and $6000\,\mathop A\limits^o $ is
- A$3 : 1$
- ✓$2 : 1$
- C$1 : 2$
- D$1 : 3$
✓
Answer
Correct option: B.
$2 : 1$
b
$E = \frac{{hc}}{\lambda };\,\frac{{{E_1}}}{{{E_2}}} = \frac{{{\lambda _2}}}{{{\lambda _1}}} = \frac{{6000}}{{3000}} = 2:1$
$E = \frac{{hc}}{\lambda };\,\frac{{{E_1}}}{{{E_2}}} = \frac{{{\lambda _2}}}{{{\lambda _1}}} = \frac{{6000}}{{3000}} = 2:1$
