Verified step by step guidance1
Understand that frequency (ν) and wavelength (λ) are related by the equation: c = λν, where c is the speed of light (approximately 3.00 x 10^8 m/s).
Convert the given wavelengths from nanometers to meters by using the conversion factor: 1 nm = 1 x 10^-9 m.
For the first option (λ = 595 nm), convert the wavelength to meters and use the equation c = λν to solve for frequency (ν).
For the second option (ΔE = 4.39 x 10^-19 J), use the equation ΔE = hν, where h is Planck's constant (6.626 x 10^-34 J·s), to solve for frequency (ν).
For the third option (λ = 690 nm), convert the wavelength to meters and use the equation c = λν to solve for frequency (ν). Compare the calculated frequencies to determine which source has the highest frequency.
