All of the electromagnetic spectrum can be reflected. White light is a combination of all colors. They all reflect, red is among them.
A white object under red light will appear red. This is because white objects reflect all wavelengths of visible light, including red light, while absorbing little to no light. The white object will reflect the red light, giving it a red appearance.
Red cloth illuminated by white light will reflect the red portion of the light spectrum, making it appear red.
When red light shines on a red object, the object will reflect the red light and appear red. If white light shines on a red object, the object will absorb all colors except red, which it will reflect, making it appear red as well.
Red objects reflect red light and absorb other colors of light. This means that when white light shines on a red object, the red wavelengths are reflected back to our eyes, making the object appear red.
It would appear to be red because it can only reflect the red light.

They will look red. This is because red boots only reflect red light. If white light was shining on them then they would still appear red because the red light would be reflected into your eyes and the other colours from the spectrum would be absorbed. However, if, for example blue light was shining on them, they would look dark/black because there is no red light to reflect.
It will look red. White light is made up of a spectrum of many colours. The primary colours are red, green and blue. An object (in white light) appears yellow because it reflects red and green light but absorbs blue light. In red light, the same object will simply reflect the red light. Since there is no green light, the object will appear red. (A mixture of red and green gives yellow)
When a red light hits a white object, the object reflects most of the red light wavelengths while absorbing others. This selective reflection gives the object its white appearance, as white objects reflect most of the visible light spectrum, including red light.
A red flower looks red because it absorbs all colors of light in the visible spectrum except red, which it reflects. When white light, which contains all colors, hits the flower, the red part of the light spectrum is reflected off the flower and that is what we see as the color red.
We see color based on the way objects reflect light. Different wavelengths of light are different colors, and the light that an object reflects is what we see. For example, a red ball reflects red light, and so we see the ball as red. Any light that the object doesn't reflect is absorbed, so the red ball would absorb all the light that isn't red. This light then turns into heat. In science, white is the absence of light, and so white objects reflect all light. This means that the object isn't absorbing any light, and so the object isn't absorbing any heat.
Photographically, both reflect about 50% of the white light falling on them, depending, of course, on their hue. A really dark blue would reflect far less than a light red, same with blue.
Paper will appear to be black under a red light because red light has a long wavelength and is less likely to reflect off the white surface of paper.
