Question

Wired Faculty App

For which frequency of light, the eye is most sensitive?

Solution

The eye is most sensitive to the light of wavelength

λ = 5600 \times 10^{- 10} m .

Therefore, its frequency is,

v = \frac{c}{λ} = \frac{3 \times 10^{8}}{5600 \times 10^{- 10}} = 5.36 \times 10^{14} Hz .
