MCQ
For which frequency of light, the human eye is most sensitive?
- A55.405 × 1014 Hz
- B95.405 × 1014 Hz
- C5.405 × 1014 Hz
- D79.405 × 1014 Hz
✓
Answer
- 5.405 × 1014 Hz
Explanation:
Human eye is sensitive to light of wavelength ➔ $\lambda$ = 5550 angstrom.
So its frequency is $\text{v}=\frac{\text{c}}{\lambda}$
$\text{v} =\frac{5550}{3 × 10^8} × 10^{-10}$
v = 5.405 × 1014 Hz
