Yes. Any two surfaces that reflects light can reflect off each other. They must have a light source though like a sun.
Planets and Moons only reflect light, they do not 'give off light'.
Only if the string is in a loop or there is something at the opposite ends of the string to provide a reflection or echo. If there is an echo then slightly weaker pulses will reflect off of each other near the point of origin.
Waves can interact in different ways depending on their type and properties. Some waves, like electromagnetic waves, can pass through each other without interacting. Other types of waves, like water waves, can reflect off each other when they collide.
People, trees, flagpoles, most animals (although the Japanese have bred "glow in the dark" fish and cats) , planets, moons, and other items that only REFLECT light.
Generally speaking, the stars do. The planets and moons reflect light back from the sun. The earth does give off some light though, in the form of artificial lighting around cities and built up areas.
If something is between them, each one will reflect the other mirror and the object between it. The first mirror will reflect the second mirror which is reflecting the first mirror, therefore the first mirror will show itself, making kind of an infinite tunnel of mirrors. There is the reflection quality to consider. The reflected image whould dim out after enough bounces.
They're considered moons. If I'm mistaking, no moons create their own light. The Sun's rays reflect off of the "small revolving body" surface and create the light we see.
are physically present in the same room and your eyes are able to see each other due to light reflecting off each other's faces and entering your eyes, allowing you to perceive the other person visually.
The particles in that object have to be either closely packed together or at least close enough for them to slide past each other. That is why you cannot see light reflecting off gas substances.
Firstly, the distances in the solar system are so great that nearly all the interactions are between the Sun and the other bodies. These include gravitational attraction, absorption of electromagnetic radiation from the Sun by other bodies, and interaction of those bodies with the solar wind. Jupiter gives off some radiation, so that should interact with other bodies, and the Earth and Moon reflect light to each other, which should apply to other planets and moons.
Planets and moons can be seen because of the light that shines off of them in space.
Planets, moons, asteroids, comets, and icy bodies like Pluto are celestial objects that can reflect light in space. These objects reflect light from the Sun or other nearby sources, making them visible to telescopes and human observers on Earth.
