Exploring SpaceRadiation from Space
![Page 2: Exploring Space Radiation from Space. Energy travels through space in the form of waves. Mechanical waves cannot travel through empty space. A sound wave.](https://reader031.fdocuments.us/reader031/viewer/2022032802/56649de85503460f94ae1b81/html5/thumbnails/2.jpg)
Energy travels through space in the form of waves.
•Mechanical waves cannot travel through empty space.
A sound wave is a mechanical wave.

Microwaves, radio or visible light waves are electromagnetic waves.
2. EM waves travel at a speed of
300,000 km/s.

5. Refracting telescope – light passes through a convex lens to form an image at a focal point.
![Page 7: Exploring Space Radiation from Space. Energy travels through space in the form of waves. Mechanical waves cannot travel through empty space. A sound wave.](https://reader031.fdocuments.us/reader031/viewer/2022032802/56649de85503460f94ae1b81/html5/thumbnails/7.jpg)
5. Reflecting telescope – light is reflected off of a concave mirror to form an image at a focal point.

![Page 15: Exploring Space Radiation from Space. Energy travels through space in the form of waves. Mechanical waves cannot travel through empty space. A sound wave.](https://reader031.fdocuments.us/reader031/viewer/2022032802/56649de85503460f94ae1b81/html5/thumbnails/15.jpg)
7. The Hubble Space Telescope is a reflecting telescope. It was launched on April 25, 1990.
![Page 16: Exploring Space Radiation from Space. Energy travels through space in the form of waves. Mechanical waves cannot travel through empty space. A sound wave.](https://reader031.fdocuments.us/reader031/viewer/2022032802/56649de85503460f94ae1b81/html5/thumbnails/16.jpg)
Hubble did not produce clear images because the mirror was not shaped correctly. In Dec. 1993 astronauts on the space shuttle replaced the mirror.
![Page 17: Exploring Space Radiation from Space. Energy travels through space in the form of waves. Mechanical waves cannot travel through empty space. A sound wave.](https://reader031.fdocuments.us/reader031/viewer/2022032802/56649de85503460f94ae1b81/html5/thumbnails/17.jpg)
8. Telescopes that orbit in space produce better images because Earth’s atmosphere absorbs and distorts energy from space – telescopes should be above the atmosphere.
