What is the difference between blue light and green light?

Answer 1

In the visible region of electromagnetic spectrum VIBGYOR, violet having highest frequency is at one extreme and red having the lowest frequency goes to other extreme. So violet with shortest wavelength and red with the longest.

Answer 2

The colors are different, but the red light is of lower frequency, lower energy and longer wavelength. The blue light is of higher frequency, higher energy and shorter wavelength.

Answer 3

their wavelengths are different.

Blue light is low wavelength, therefore high energy

Red light is higher wavelength therefore lower energy

Answer 4

Its color. Physically, both the wavelength and the frequency are different for different colors of light.

Answer 5

red and blue light differ in wave length because blue lights have shorter wave length than red light and shorter wave length are good for plants germination.

Answer 6

They're in the approximate neighborhood of twice as long.

Answer 7

The wavelength of blue light is roughly 1/2 the wavelength of red light.

Answer 8

The wavelength of red light is almost double the wavelength of violet light.
