How are the Distances between different objects in space measured?
they use light-years to determine the space between objects in space
How does light determine an objects's color?
Light determine an object's by the wavelength of light that reach to your eyes.light can reach your eyes after being reflected by an object,transmitted through an object,or emitted by an object.When your eyes receive the light,they send signals to your brain.Your brain interprets the signals as colors.
Why does objects become dimmer with distance?
As light moves through the air, it slowly diminishes, until it finally disappears. When light bounces of any object, light turns to colour. Objects become dimmer because the further back it moves, the more coloured light diminishes, causing the object to look dimmer in light and colour.

Do heavy and light objects fall from the same distance at the same rate?
yes, they wil, yo can test it out with a marble and a bowling ball
Which sense can be used to determine an objects ability to reflect light?
The eye

How can you determine distance using remote sensing?
A radar emits electromagnetic radiation via a transmitter, and it has a directional antenna that measures the time of arrival of backscattered or reflected pulses of radiation from remote objects. The distance between the radar and object can be deduced using the speed of light.
Why do eyes show different size images?
Eyes show different sizes because of the way light hits the objects and bounces off of them. The distance and angle of view may also determine the size that the eyes show.
How does these two quantities determine the speed of light?
The distance in meters covered by light in one second is considered to determine the speed of light. Speed of light is 3*108m/s. The unit of speed of light is meters per second.
How does light help us see?
Light reflects off objects and enters our eyes, where it is converted into electrical signals that are sent to the brain. The brain then processes these signals, allowing us to perceive and interpret the visual information, which is how we are able to see things.
What is a light year used for?
A light year is a measure of distance and is the distance light travels in one year's time. The light year is used to describe the enormous distances between various objects in space. In one year, light travels about 6 trillion miles.

How is the number of light years figured between two celestial objects?
To find the number of light years between two celestial objects, we first find the distance from each object to earth. If we connect the dots between Earth and the two objects, we have a triangle. We to sides lengths of that triangle (the distances between Earth and the objects), and we can measure one angle (the angle at the vertex where Earth is. This is enough information to find the distance between the objects using trigonometry (in this case, the law of cosines). Finding the distance from Earth to an object can be a bit complex. One commonly used method is to look for a pulsating star. We can figure out the absolute brightness (how bright it is without factoring in distance away) of these stars by how often they pulse. Then we can measure the apparent brightness (how bright it looks to us). We can then use both these values to find the distance to the star. (This also works for some supernovae.) Another method is to use objects that are considered to be 'standard candles'. These objects do not pulse, but we know the relationship between their absolute brightness, apparent brightness, and distance away.
What is the light year?
The light year is a unit of distance, used in connection with the distribution of astronomical objects throught space. It's defined as the distance traveled by light through vacuum in one year, and when rounded, is roughly equal to 5,878,600,000,000 miles. The distance to the nearest star outside the solar system is about 4.3 light years.
What does distance mean?
The space between two objects or points. Distance is by definition measurable, so that if one asks what the distance is between two objects, one answers in units of two-dimensional spatial measurement (metres, feet, inches, miles, light years etc.)
What is a light parsec?
"Light-year" and "parsec" are two units of length used in Astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.
