For which frequency of light, the human eye is most sensitive?(a) 55.405 × 10^14 Hz(b) 95.405 × 10^14 Hz(c) 5.405 × 10^14 Hz(d) 79.405 × 10^14 HzI got this question in an online interview.My question is taken from Electromagnetic Waves in division Electromagnetic Waves of Physics – Class 12

Answer» CORRECT answer is (c) 5.405 × 10^14 Hz

To EXPLAIN: HUMAN EYE is sensitive to light of wavelength ➔ λ =5550 angstrom.

So its FREQUENCY is v = \(\frac {c}{\lambda }\)

v = 3 × \(\frac {10^8}{5550}\) × 10^-10

v = 5.405 × 10^14 Hz
