Question

Chlorophyll present in green leaves of plants absorbs light at 4.620 X 1014 Hz. Calculate the
wavelength of radiation in nanometers. Which part of the electromagnetic spectrum does it
belong to?

Answer 1

Answer: 649.4 nm; visible light

Explanation:

λ=v/f ( wavelength = velocity/frequency)

f= 4.62 x 10^14 Hz or s^-1

v = c = 3 x 10^8 m/s  (speed of light)

so λ = $\frac{3 X 10^8}{4.62 X 10^{14} }$ = 0.6494 x 10^-6 m

0.6494 x 10^-6 m x 10^9 = 649.4 nm

Thus, it belongs to the visible spectrum of light

Answer 2

Answer:

0.6494 x 10^-6 m x 10^9 = 649.4 nm

It belongs to visible spectrum of light
