Question

The wavelength of the color red is about 6.5 × 10−9 m. The wavelength of the color blue is about 4.75 × 10−9 m. Show that the wavelength of red is longer than the wavelength of blue.

Answer 1

2.5x10^-7m that’s the answer

Answer 2

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.
