Why does the apple appear red in red light and nearly black in green light?

In white light, a red apple absorbs all the colors (including green) of the spectrum except red, which it reflects. … When the green light shines on a red apple, the red apple absorbs the green light. Since there is no red light shining on the apple, there is no red light to reflect, so the apple appears black.

Why a red apple would appear black if you looked at it through a blue filter?

Under blue light, an apple will appear black because it absorbs the blue light and has no red light to reflect. In contrast, if magenta light is shined on the apple, it will appear red because magenta light is comprised of red and blue light. The blue light will still be absorbed, but the red will be reflected.

Why does an apple appear to be red?

Red apples get their color from anthocyanins. … When we look at a red apple, it’s absorbing colors from the sunlight. It absorbs all the colors of the rainbow—except for red. The red light reflects off the apple and our brain and eyes work together to let us know what color we are seeing.

What colors of light are reflected and/or absorbed by a red apple when?

An apple is red because it reflects red light and absorbs blue and green light.

Why do we see different colors?

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. … White objects appear white because they reflect all colours.

Which colors are reflected by a red apple?

A red apple looks red because it reflects the red portion of the spectrum while absorbing blue and green. A green apple reflects primarily green while absorbing red and blue.

Why does an apple look red use absorption reflection and white light in your explanation?

The color that you see is the reflected light. An apple is red because when white light reaches the apple, the apple absorbs all of the colors of the rainbow that exist in that white light, except for red. The red light, which isn’t absorbed by the apple, is reflected into your eyes. And so you see the apple as red.

Is an apple still red in the dark?

If it’s dark, you can’t see apples, so they aren’t red. Similarly, the redness of apples is contingent on you being able to see, the ambient light being white (under blue light apples will be bluish), and your brain working well enough to put visual stimuli together with labels for colors.

What color will the apple appear to be if it is illuminated by red color light?

the white light are absorbed except the red light which is reflected. Since blue light one of the primary colors (and does not contain red light), when it illuminates a red apple the apple would appear black since there is no red light to be reflected back.

When you look at an apple and see it is red what is actually happening to the wavelengths of light hitting the apple?

We see only the red reflection, thereby producing the red color of the apple. This is true of all colored objects. Special color filters (such as the ones included with this activity) appear transparent (yet only one color), and only allow light from a narrow band of wavelengths pass through.

Why is an apple red electromagnetic spectrum?

As you know, the visible portion of the electromagnetic spectrum corresponds to a wavelength interval that starts at about 380 nm and ends at about 760 nm . … For example, we perceive an apple as being red because its constituent molecules absorb all wavelengths of light except red.

Do apples reflect light?

You can see that the apple reflects quite broadly between about 550 and 600nm. That includes all of the wavelengths we associate with yellow and orange as well as red. The apple even reflects nearly 10% of the light at 400nm (which we normally associate with blue) that falls upon it.

Why are different colors seen in the visible portion of the electromagnetic spectrum?

All electromagnetic radiation is light, but we can only see a small portion of this radiation—the portion we call visible light. … As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength.

What does the person see if you put red light through a red filter?

An ideal red filter transmits only red light and absorbs all other colors. In this ideal case, a picture containing red, green, and blue would appear red and black when viewed through a red filter. A red filter blocks green light and blue light: Only red light can get through to your eyes.

What can the human eye not see quizlet?

What can the human eye not see? Infrared radiation.

Why do we see the sky in reddish color during sunset?

At sunrise and sunset, the Sun is very low in the sky, which means that the sunlight we see has travelled through a much thicker amount of atmosphere. … The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer wavelength yellow and red light.

What color is seen when an object reflects all the colors of light?

white
A white object reflects all colors of white light equally.

What is the position of the red color in the visible spectrum?

Visible red light has a wavelength of about 650 nm. At sunrise and sunset, red or orange colors are present because the wavelengths associated with these colors are less efficiently scattered by the atmosphere than the shorter wavelength colors, such as blue and purple.

Is sunset red a color?

During sunset hours, the light passing through our atmosphere to our eyes tends to be most concentrated with red and orange frequencies of light. For this reason, the sunsets have a reddish-orange hue. The effect of a red sunset becomes more pronounced if the atmosphere contains more and more particles.

What does red look like in red light?

Red coloured objects don’t look red in the presence of red light only. It looks more red in colour. You may have not observed it right. Although it appears the same as a white object, both would actually appear red since they are both reflecting the illuminated light.

Is white a color?

Is white a color? … Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they’re shades.

What color best reflects light?

White light contains all the wavelengths of the visible spectrum, so when the color white is being reflected, that means all wavelengths are being reflected and none of them absorbed, making white the most reflective color.

Why does an object look red in white light?

In most cases not all the light is absorbed by the surface and the light that is not absorbed is scattered. … A red object is red when white light falls upon it because it absorbs all the components of white light with the exception of the red component which is scattered.

Why a red flag appears red in white light?

A red jumper is red when viewed in white light because all the wavelengths of the spectrum that fall on it are absorbed except red which is reflected into the eye.
