When was a telescope first used in space?
The first telescope used in space was the Orbiting Astronomical Observatory 2, or OAO-2, launched by NASA in 1968. This marked the beginning of a new era in space-based astronomy, allowing scientists to observe celestial objects without the distortion caused by Earth's atmosphere.
Who are the famous scientist who contributed in motion?
Isaac Newton is a famous scientist who made significant contributions to the understanding of motion with his laws of motion. Other renowned scientists who have made contributions to the understanding of motion include Galileo Galilei and Albert Einstein with his theory of relativity.
How did Galileo attempt to measure the speed of light?
Galileo used two distantly-separated lanterns in his experiment. Galileo knew that light traveled very quickly, but did not appreciate how fast it really is. Standing on a peak at night with a shuttered lantern, he sent a colleague with another lantern to a peak some miles away, where the lights would still be visible to each other when opened. At a prearranged time, Galileo would uncover his lantern. The colleague, when he saw the light from Galileo's lantern, would uncover his own lantern, so that Galileo could then see it. The time between Galileo's uncovering and the time he saw the other lantern would be the time it took light for a round trip equal to twice the distance they were apart. The result, as would be expected today, was that the colleague saw the light practically as soon as Galileo uncovered it, and uncovered his own, which was then visible practically instantaneously to Galileo. No matter how far apart they were, the brief time lag was identical. Considering the reaction time by the assistant, and the time taken to open the lantern, Galileo reasoned that light traveled far too quickly to be measured.
Why did Galileo want to find out what the speed of light was?
oh Galilieo
What did Galileo's first telescope look like?
Galileo's first telescope was a simple refracting telescope consisting of a convex objective lens and a concave eyepiece lens. It had a very small aperture size and low magnification compared to modern telescopes. Galileo used this telescope to make significant astronomical observations, such as the craters on the Moon and the moons of Jupiter.
Who was the scientist who discovered that heavy and light body of the same substance fall at the same speed?
Galileo Galilei, an Italian scientist, is credited with the discovery that heavy and light bodies of the same substance fall at the same speed in a vacuum. He conducted experiments to demonstrate this principle of free fall.
Which scientist first discovered that white light is a mixture of a rainbow spectrum of light rays?
Isaac Newton was the scientist who first discovered that white light is a mixture of a rainbow spectrum of light rays through his experiments with prisms in the 17th century.
Which scientist first discover that white light is a mixture of rainbow spectrum Leah which scientist first discover that white light is a mixture of rainbow spectrum?
Isaac Newton is credited with being the first scientist to discover that white light is actually composed of a spectrum of colors. He achieved this by passing white light through a prism, which separated it into its component colors, creating a rainbow spectrum.
What scientist invented the first light bulb?
Thomas Edison is credited with inventing the first practical incandescent light bulb in 1879.

Who determined that the moon was not a source of light but reflected light?
Galileo
When was the light bulb officially invented?
The first electric light was made in 1800 by Humphry Davy, an English scientist.

What did the lamp do in Galileo's experiment?
it gave off light

How does a spectroscope extend a scientist's ability to observe light?
It allows a scientist to measure the wavelength of light.
