100 POINTS!!!

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.

Pls answer asap 100 points

Answer 1

Step-by-step explanation:

To tell if something is longer than another object is to find the difference between the two objects.

If the difference is < 0, then the object is shorter

If the difference is = 0, then the objects are equal in length

If the difference is > 0, then the object is longer

`6.5 * 10^(-9)` -
`4.75 * 10^(-9)` =
`1.75*10^(-9)`

The difference is > 0, so the wavelength is longer.

Answer 2

2.5 x 10^-7 m
Step-by-step 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 × 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^-7m longer than violet light.
