Homework help: In what way does red light differ from green light?

Question

science question.
im completely stumped, ive gone over the whole chapter over and over again but i cant seem to answer this question.
we are learning about light
reflection and refraction
help?

Answer 1

The above answer about the wavelengths is incorrect. Red has the longest wavelength and violet is the shortest wavelength in the visible spectrum.

Besides wavelength differences, they also have frequency and energy differences.
Green has shorter wavelength, higher energy and frequency
Red has longer wavelength, lower energy, and frequency

In terms of reflection and refraction, the light refracts differently and reflects differently due to its wavelengths. If they reflected/refracted the same, one would not get a spectrum out when white light is passed through a prism. Because of different refraction angles for the different colors one sees a seperation of light when it is passed through the prism.

Answer 2

Red light has a different wave length than green light. Red light is at the low end of the visible spectrum. Green light is in the middle. Blue light is at the high end.

I don't know if you've been given this. It can be confusing, but it's true. The primary colors of PIGMENT are the familiar red, blue and yellow. But, the primary colors of light are red, blue and GREEN. You get yellow light by mixing red and green. You get white light be mixing all the colors together.

If you shine a beam of white light through a prism, the different wave lengths of light are bent (refracted) at a different angle. So, at one end you will see red; in the middle, you will see green, and at the other end, blue.

When light hits something, one of three things will happen. The light will be absorbed, transmitted or reflected. If a beam of white light hits a red object, all colors of light are absorbed but red. The red is reflected, and so you can see it. If you shine a red light on a blue object, the object will absorb the red light, and you will see nothing. Nothing is black.

I hope I helped a bit.

Answer 3

Different colors of light have different wavelengths.
When white light enters a prism and is refracted, a rainbow exits from the other side of the prism.
In other words, different wavelengths of light are refracted at different angles.
One interesting and practical situation: When blue light enters the human eye, it's more likely not to be focused on the retina than other colors. The angle of refraction is greater than with other colors, such as red. Hence you can often sharpen your vision by merely blocking out the blue end of the spectrum--with so-called "blue-blocker" dark glasses.

Answer 4

Wave legnth. Red light has a short wave legnth. The light specrum goes: red, orange, yellow, greeb, blue, indigo, violet in order from shorter to longer wave legnth.

P.S. sorry, but photosynthesis has nothing to do with it. In the fall, leaves change color and become yellow, orange, or red. If the leave could no absorb green light, the leaves would not turn red but stay green all year.

Answer 5

It has to do with photosynthesis. Leaves can absorb red light, but they can't absorb green light; hence, the green color.
