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.
Is a conductor of the heat. Hope this helps!

<span>The period of a wave can be calculate according T = 1 / f
where T is wave period and f is frequency,
then in our problem we have a wave of 100 Hz so:
T = 1 / 100 = 0.01 seconds
The wave have a period of 0.01 seconds.
Optinaly we could also calculate the speed: V=wavelenght/period= 2/0.01= 200 m/s</span>
