Answer:
2.5 x 10^-7 m
Explanation:
We can substract the wavength of the violet light to the wavelength of the red light:
(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m
This is the difference between this two values of wavelength.
So the wavelength of red light is 2.5 x 10^-7 m longer than violet light.
