Question

5. What color of visible light will have a frequency of 6.20 x 10¹4 Hz? Show your

work. Remember! 1 meter = 10° nanometers

Answer 1

483 NM answer

First, we calculate the energy:

E = hf = (6.626 x 10^-34 J s) x (6.20 x 10^14 Hz) = 4.11 x 10^-19 J

Next, we can use the equation E = hc/λ, where c is the speed of light and λ is wavelength, to find the wavelength:

λ = hc/E = [(6.626 x 10^-34 J s) x (3.00 x 10^8 m/s)] / (4.11 x 10^-19 J) = 4.83 x 10^-7 m

Finally, we convert the wavelength to nanometers:

λ = 4.83 x 10^-7 m x (10^9 nm / 1 m) = 483 nm
