How did Archimedes use light during second Punic war in 218 to 201 BC?
In the defence of Syracuse, he used parabolic mirrors to focus the sun's rays into a column of heat directed at approaching wooden warships of the Roman fleet, setting them on fire.
What did Diocles do?
Diocles was a prominent ancient Greek mathematician and astronomer, active around the 2nd century BCE. He is best known for his work in geometry, particularly for his studies on burning mirrors and their properties, as well as his contributions to the understanding of parabolas. Diocles also authored a significant work called "On Burning Mirrors," which explored the principles of optics and the focus of light. His investigations laid the groundwork for later developments in both mathematics and physics.
What is the main purpose of a focus group?
The main purpose of a focus group is to gather qualitative insights and opinions from a diverse group of participants about a specific topic, product, or service. This method allows researchers and marketers to understand participants' perceptions, attitudes, and motivations, which can inform decision-making and strategy development. Focus groups facilitate in-depth discussions, enabling the exploration of ideas and the identification of trends that may not emerge through quantitative research methods.
A microscope with only one lens is call what?
A simple microscope an electron microscope is one that uses the focus of electron beams instead of regular light from lenses. It allowed scientists to discover new germ cells, bacteria, and eventually viruses. the simple microscope was invented in 1600s
How did mob football reflect pre-industrial Britain?
The focus on small rural communities in pre-industrial Britain was the basis for mob football. It was used as a way for the people to gather, celebrate, and just have some communal fun. The Industrial Revolution led to extensive flight from these communities to the city and devalued the importance of mob football.
What type of telescope uses lenses or mirrors to gather focus light energy?
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.
What type of telescope uses lenses or mirror to gather and focus energy?
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.
Uses lenses or mirrors to gather and focus starlight?
optical telescope
Does the Hubble Telescope use mirrors or lenses to focus the image?
The Hubble Telescope uses both mirrors and lenses to focus on images.
This telescope uses mirrors to gather and focus light energy?
Newtonian telescope
What is the name of the telescope that uses convex lenses to gather and focus light?
Refracting telescope.
A telescope that uses a set of lenses to gather and focus light from distant objects?
Refracting Telescope.
What instruments use lenses or mirriors to collect and focus light from distant objects?
Telescopes use lenses or mirrors to collect and focus light from distant objects. The lenses or mirrors help to magnify the light and form an image that can be viewed by the observer.
Does the hubble space telescope use mirrors or lenses?
The Hubble Space Telescope uses mirrors to gather and focus incoming light. The primary mirror is 2.4 meters in diameter and collects light from celestial objects to produce high-resolution images. Mirrors are well-suited for space telescopes as they are more durable and easier to shape to precise specifications compared to lenses.
What instruments use lenses or mirrors to collect and focus light from distant?
A telescope uses lens and mirrors to collect and focus light from distant object.
Which of the following statements best describes the difference between a refracting telescope and a reflecting telescope?
A refracting telescope uses lenses to gather and focus light, while a reflecting telescope uses mirrors. Reflecting telescopes are often preferred for large astronomical telescopes because mirrors can be made larger and more easily than lenses.
What device use lenses or mirrors to collect and focus light from distant object?
That device is a telescope.
