Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
Answer:
23.5º
Explanation:
The Earth has a tilt of 23.5 degrees on its axis. This tilt causes the seasons because certain parts of the Earth are naturally tilted towards the Sun more depending on the Earth's location in its revolution around the Sun. The Tropics of Cancer and Capricorn are located at 23.5º North and South of the equator respectively, and this number comes from the tilt.
Have a wonderful day! :D
The answer is B- 43 degrees North.
